how can i create custom interfaces in xcode 4? i've seen programs like Kaleidoscope (http://designshack.co.uk/images/designs/kaleidoscope-for-mac.jpg) using custom controls or something not available for drag and drop on xode.
any help? thanks

You'll get better help if you take the time to craft more specific questions.
Since you're speaking generally, I'll answer generally: Xcode 4 will not help you create custom interfaces (at least not beyond letting you edit the code to build them). This is done entirely in code.
Learn to draw with Cocoa then learn how controls and cells work, then ask specific questions when you don't understand.

I am a newbie in cocoa . I really can't understand how to use NSTableView. Searched for a good example but couldn't find. Can anyone help me?
Google search resulted in some huge coding. but I think there must be some easier way
in Cocoa.
"Huge coding" is relative. You won't be able to implement a table with just a couple of lines of code. Implementing the data source and delegate methods of the table view will take at least 100 lines if not more. See Populating View-Based Table Views Programmatically.
An alternative might be using Cocoa Bindings to bind the content of your table view to an NSArrayController.

I'm trying to use Xcode 4's Interface Builder, but I'm a bit lost when it comes to some of the terms being used. I'm not familiar with File's Owner, delegates, controllers, etc.
Is there a good tutorial out there that can explain how to use Interface Builder, what these terms mean, and how I can use Interface Builder to properly connect my UI elements?
You want the Cocoa Fundamentals Guide. Read it beginning to end.

i never work with DLINQ so i dont know the use of DLINQ. so can anyone show the situation where DLINQ is required and also show me the various use of DLINQ.
"While writing type-safe queries is great for most scenarios, there are cases where you want the flexibility to dynamically construct queries on the fly. For example: you might want to provide business intelligence UI within your application that allows an end-user business analyst to use drop-downs to build and express their own custom queries/views on top of data.

I am starting a new project which have an interface like picasa 3. Please let me know what all documents i have to prepare in advance before starting the project. Right now i am only developer but in the future other developers may join.
Is there any third-party components which will help me simplify the task of theming and creating buttons?
Thanks in advance,
John
Indeed your question is actually 2 questions. For things to prepare when starting a development project:
schedule and cost estimation report (use a cost estimation software)
project design specification
project logical block diagram (can be UML or just Visio)
technological feasibility report
business presentation based on the above documents
depending on your venture model, you may be required to present your investors with further reports and presentations.

It looks like you're not sure what you're asking. Perhaps go and research the general idea of steganography.
Short answer: don't.
Slightly longer answer: it's a very inefficient form of steganography, it won't work for JPEG images, and for GIF/PNG it'll basically make your image uncompressable.
If you need stega for anything else but curiosity or school assignments, research existing offerings.
The technique you're thinking of is called Steganography. Here's a good post which explains the technique. http://www.dreamincode.net/forums/topic/27950-steganography/
