I'm working on a Project with outdated, very old looking GUI (the used GUI framework is more than 10 years old)
Since the used programming language is Eiffel, there are almost no good libraries for GUI development. Although Wrappers for C libraries exist, it's not that easy to wrap something like Qt with them.
The current GUI framework uses the Windows API to create windows, widgets and so on. But as stated - it's very old.
Now i would like to learn more about how to use the Windows API directly to create state of the art GUI's
Can someone recommend any reading material?
"Windows Programming" by Charles Petzold is an excellent start on Win32 API programming.
It won't show you how to create a WPF-grade interface but it will show you how to create a basic average application.
It doesn't take a lot of surgery to turn on Windows Visual Styles and get an instant new look. If your toolset doesn't allow creating resources then take a look at mt.exe in the Windows SDK.

As SO returns "4,476 search results for posts containing "win32 gui applications""... I'll have to ask a question that has probably been asked before but is lost in the midst of all those questions.
Currently, what are the options to write GUI applications for Win32, that have a big-enough following so that the environment offers enough and well-supported third-party tools?
I could come up with:
C++
Delphi, and possibly
RealBasic (although the fact that it's originally a Macintosh tool could result in small but noticeable issues in look 'n feel).
Besides their relative lack of well-supported third-party tools, solutions like Python + wxWidgets, or [Power|Pure|Free]Basic aren't good options: The former has too many 1.0 widgets (couldn't find a business-grade grid, for instance), and the latter are procedural languages so requires writing apps like Petzold's book with the lower productivity it entails.
Are there other solutions available?
Thank you.
Edit: Sorry for not having been precise enough: Big tools like .Net and Java are not options. I'm looking for tools that can either build a whole EXE statically (eg. Delphi) or provide a light enough runtime (VBClassic).
If you are new to programming I would suggest C# as well if you are only looking to make this app for the Windows Platform however with tools like Mono it can be ported to OS X and Linux Platforms.
Windows has their own IDE just for this called Visual Studio Express C#
Visual Studio's C#
As well as a version for C++ if you are wanting to say in that programming language.
The Mono project allows you to use C# in Linux and Mac as well as port the apps to iOS and Android

You Can use C++ or You can even use the .net framework to develop your windows applications. .Net framework have lots of opensource contributed modules and paid modules and well as number of resources all over the internet to speed up the development compare to other options you have mentioned.
If you are going for a windows 32 gui application, I would prefer to go with .net framework, C++.
Java Swings also another best options which is platform independent as well.
You can use Lazarus as a free alternative to Delphi. Potentially you will have a very high possibility to check its "write once, compile anywhere" motto if you later decide to port your Win32 application to Linux or MacOS. In ideal case it will just work, but in reality you would probably need some conditional defines sections.
Some articles point to Windows 8 development being HTML-based instead of primarily using native code like C or C++ (as it has been until now) or .NET (as now, or even more so as it would have been in Longhorn, but never was.)
Is this true? Will the core APIs be accessible from Javascript then? What is the primary API / framework for Windows 8?
This is worth asking. When Windows 8 was demonstrated in June, a couple of comments by the presenter scared quite a few developers - or at least turned the Internet into panic mode. I'm surprised this question hasn't been asked here before.
The best article on the topic I have found is Windows 8 for Software Developers on Ars Technica.
The short answer is: it will remain the same.
The long answer is: it will remain the same, but several things will be added. You may want to pursue using those if you're willing to bet on new Microsoft technologies. One particularly interesting one is WinRT, which is a new object-oriented native code API exposed through COM, which is supposed to be a new version of the old flat Win32 API. Details are in the linked article.
It is very, very, very, very unlikely that anything that already exists, especially based on Win32 or .Net, would be removed. That means your existing programs written in .Net or native C++ or Delphi will continue to work fine. It is also unlikely that the primary development platform will be HTML. More likely is that HTML applications will be encourage for specific scenarios - perhaps touchscreen, kiosks and tablets.
I'd encourage you to read the article I linked to above - it covers this in far more detail than any answer here can.
There are three ways to develop for Windows 8, and they all access the same underlying API, the Windows Runtime.
Use C++ and call WinRT functions much like calling Win32 APIs back in the day (you know, yesterday)
Use C# or VB and call what appear to be .NET methods (but aren't)
Use Javascript and call WinRT functions
The UI is built with XAML using a pretty reasonable designer. More details are still coming out: check http://channel9.msdn.com/Events/BUILD/BUILD2011 for videos with detailed coding demos. http://channel9.msdn.com/Events/BUILD/BUILD2011/BPS-1005 is not a bad starting point.
There are 3 language/framework combinations that are all equally supported:
C++ and XAML
C#/VB and XAML
JavaScript and CSS/HTML
All are first class ways to write Windows 8 Metro style applications. Windows Runtime provides direct access to each of these languages and so choice of development environment can be based on familiarity or feature set of the language and not on restricted availability.
Update: I forgot one: C++/Direct3D (for games).
The original quote, in the context of writing a tablet desktop weather gadget application, is that the application uses "our new developer platform, which is, uhh, it's based on HTML5 and JavaScript."
The demonstrator never said a gadget is the preferred type for applications (How many Vista sidebar gadget or Windows 7 desktop gadget have you written in your life? Even when you can write them in simple HTML!), or the platform is the preferred platform for desktop weather gadget applications (How many animation control have you add to your application with video playing requirement? It is THE control used by Windows Explorer to display video!).
Today, after spending a few minutes playing with Windows 8 developer preview, I found that you can use Expression Blend 5 to easily auto-generate metro-styled applications in HTML and Javascript. Also in Visual Studio you can create exactly looking applications in Silverlight. :)
I am very excited!!! Go Windows 8! :)
I have a few years of experience writing Unix command line tools (no GUI experience) in python, C and C++, and only recently crossed into the GUI world (Cocoa and IOS only). I've learned quite a bit of objective-C and am getting to understand how cocoa MVC works. However, one of the apps I am developing needs a Windows version and I was wondering what a good place to start would be given that I have absolutely no Windows development experience.
I was thinking about using Visual C++ 2010 Express as my development platform (because it's free and because I don't need to learn C++). My application is relatively simple, it will have only two windows and spend most of the time running in the background. It will however need to communicate with the OS (load dll's etc) and an online server (HTTP methods) and I'm not sure whether Visual C++ Express edition gives me access to the required API's. Would a Windows Forms application suffice? Am I going about this the wrong way? Do I need to learn C#? Any advice will be appreciated.
If you are already happy with proper c++, visual Studio C++ express should suit you fine. Given that you are not making a complicated GUI, you don't even need to dip into the managed code - C++ express allows you to create proper c++ console and GUI apps. You also don't need to install the platform SDK - it is part of VS C++ express.
Not being managed C++, you will be able to share source files between your various projects. managed c++, despite the c++ in the name, really is a different enough language that it will be annoying to work with if you simultaneously have to deal with iso C++.

Note: The native windows API is a C api, not a C++ framework. So it does not provide a rich set of classes in a coherent framework to deal with. On the other hand, while, large, it is actually quite simple to work with.
Also: Given that you are already familiar with Mac development, there is a LGPL (iirc) package called CFLite that builds on windows and that implements the C api that underlays the Objective-C Cocoa API.
If you use its abstratcions you can share a greater part of code between windows and Mac (and other platforms).
Other C++ IDE's you might want to consider:
Code::Blocks
QT Creator
both of which can be configured to use the MINGW port of GCC to windows.
you'll be better off with c++ than c# if you need more "low-level" stuff. Loading dlls (that is, libs) is simple (pragma comment lib...), as is pure HTTP transfer and communication.
So, VC++ with windows form will suffice, and it is "very c++".
You have access to all global APIs, and loading specific apis like http requires only two lines: one to include wininet header, and other lib (libs are actually "references" to dlls).
If you go the C++ Express way then you need to install Windows SDK separately, and set it up for Visual Studio to use it. And you can't use MFC.
I would however, suggest C#, because it feels like putting little toy bricks together. Easier to debug and maintain. Problem with C# is that it has so many library functions that you can not possibly know if what you want is already made to a function. But that's why we are here :-) If you feel that something you want to do should already exist then ask a question about it. One notable feature that C# lacks is zip archives (it has something similar, but not quite). For zips you can use public libraries, like SharpZipLib or DotNetZip.
If I were you, I wouldn't jump into a whole new API so quickly. Have you considered using Python on Windows? Most of the Python packages I've seen are also available for Windows, so you'll feel at home. And if you need some GUI, you can opt for wxPython, pyGTK or something similar.
For Windows specific things, you can always use ctypes. Especially if they're as simple as loading a DLL.
have you considered approaching Adobe AIR? it allows you to deploy on Mac, Linux, Windows, iOS, etc. communicating with and launching native processes has been possible since 2.0 and the the latest 2.5 SDK can target Android OS and TVs. with your experience you should be able to pick up ActionScript3 / MXML in no time.
additionally, there are a handful of free IDEs you can use with the Flex and AIR SDKs. or, if you're a student or low-income developer, you can get a free copy of Flash Builder 4 from Adobe: http://www.adobe.com/devnet-archive/flex/free/
edit: i believe deploying AIR applications on iPhone requires Flash Professional CS5, which includes the packager for iPhone options. at the same time, i've read that AIR and other cross-compilers for iOS are painfully slow, so it's perhaps best to develop natively in Objective-C for iOS.
I've been doing web development for about six years now, and somehow have entirely avoided ever developing a desktop application.
I am considering writing a desktop application (I'm thinking something similar to a Word clone) on Linux but have no idea where to start. I hear of Qt and GTK+, but I'm curious if there are any frameworks that are similar to web development. Language isn't a problem, as long as it isn't Java.
You really want to go with Qt these days. Both Nokia and Intel are now pushing it as the main GUI in their new distro Meego. This means, if you are using Qt, you'll be able to target all their platforms (both desktop, embedded and phone domain), including all the platforms already supported by Qt.
Qt also comes with a GUI Designer and an IDE which will support you in the whole process, and soon there will be QML, which is a declarative UI language, for even more rapid development of apps.
Take a look here:
http://qt.nokia.com/products

GTK+ and QT are GUI frameworks. They use xlib under the hood and encapsulate the nuances of xlib and provide you with an easier interface.
For rapid development you can use GLADE and quickly build GUI applications in C/C++.
Check out wxWidgets, it's another framework that is usually compared with Qt & GTK+
Go for Qt. And, if you are webdev, you will find in QML one of the best instruments EVER.
It has:
A Declarative approach to UI definition and Graphics elements Behavious/Animations
It's cool and simple at the same time
For now is only available in a couple of (old) binary drops, or by clone-compiling qt.gitorious.com/qt, branch ">4.7"
If you don't have to release today, but do you have time to develop and test, then QML should be "stable" by end H1 2010. If I got the schedule right ;-)
We are planning to develop an application for monitoring and configuring our service (which is running on remote server). After long time of discussion, we decided for python as platform for our app, because we love and know python. But we don't know, what GUI toolkit preferred for our aims. We need fast (for development and running) app, whose users will be Admins, Maintainers and Account managers.
There are two GUI toolkit for python, which we know: wxPython and pyQT.
Anybody have arguments regarding pro and cons? And maybe someone knows any commercial applications, using these products (only python version of toolkits)? Links are desirable.
Thanks.
I choose wxPython after much research. The reasons were:
"wxPython in Action" book by Rappin & Dunn
The voluminous examples that come as part of the wxPython download
The number of projects that have used wxWidgets
The fact that wxPython code runs equally well on Linux, Mac OS/X and Win32
I did consider pyQT and other researchers are successfully using it. After writing many examples in all API's that I considered, I found wxPython ticked the most boxes for me.
As for Tkinter (TIX), I think it looks rather dated.
Unless you are using IronPython or Jython I would not consider using the associated native windowing APIs. For another project which is to be delivered exclusively on .Net, I plan to use WinForms after lots of great feedback from StackOverflow members.
Well, I am a fan of QT: it has a more modern look and feel. However - your choice should be based on your actual requirements. Simple trade studies are helpful for this. Make a list of what features your toolkit must have and what features would be nice to have and then weight each item appropriately. Then look at all your options (TKinter also) and then score them according to your feature list (using the weights you assigned to each feature requirement). At the end it should be evident which one is right for your project.
I've always liked Qt's "signals and slots" conceptual model, though I guess it may take a bit of learning for developers who are more used to other models of event propagation and handling. Personally, given a choice, I'd pick PyQt because of this programming aspect.
You wrote "There is two GUI toolkit for python, which we know: wxPython and pyQT." You are forgetting about the most obvious toolkit: tkinter. That's actually part of a core python distribution, no extra downloads required.
Some people don't like Tk but that's often due to ignorance. Tk is a fine choice for a cross platform toolkit. It uses native widgets on windows (and has for many years) and the latest versions of tk use themed widgets on all platforms.
i've been using wxpython for 3 years .. and now we had to switch into pyqt since qt is integrated in maya 2011 .. however , wxpython is more straight forward and you can easily start working on it and learn it from zero fast .it provides and awesome resources and decumentation . but QT provides more powerful features that you cant find in wxpython , for example ( the multi touch detection) , QT also provides good support for drawing devices like pc tablets and so on .
qt also provides a good designer that makes u create interfaces faster.
one of qt disadvantages is it's license since it's not free like wxpython
A Windows (and Mono) option for a GUI toolkit is provided by IronPython. It provides access to the Winforms and WPF libraries. For examples, see Developing with IronPython & Windows Forms, and many others.
If you want to expand the list of options, consider building a Web App instead of a (local) GUI app. You say your service runs on a remote server, so networking is part of your requirements.
Once you start down that road, Python provides a bewildering amount of options.
I want to point out two strengths that wxPython has compared to pyQt:
It uses native widgets on every supported platform. So the apps have a native look and feel. I'm aware that PyQt uses native styles, but the behavior ("the feel") is reported to be somewhat non-native especially on the Mac.
It provides a wider choice of widgets out of the box.
You should also check out PyGTK. It is similar to pyQT in programming model but does not have any licensing cost since it is LGPL. I always found it nice to work with as a developer. The main drawback over pyQT is that in some cases they take away functionality in things like file chooser dialogs in favour of simplicity for the user.
