Qt Windows Deployment Process - windows

Question

I am in the process of learning how to create applications using Qt. I created a small app that is running fine on any machine that has Qt installed. I want to deploy using dynamically linked Qt libraries to Windows. I followed the instructions found here and with some help of other Stackoverflow articles I was able to get the application running without error, but now nothing shows up. There should be a small UI with buttons and such, but it isn't being displayed despite the fact that Windows Task manager reveals that the application is running.
My first thought was that I was missing some dll files, but even if I copy every dll found in C:\Qt\5.5\msvc2013_64\bin, the entire C:\Qt\5.5\msvc2013_64\plugins directory, msvcp120.dll, msvcr120.dll and the plaforms\qwindows.dll to the application directory I still cannot get it to display the UI.
The same application will run on any Win x64 machine with Qt installed. I just don't find asking users to download a 700mb set of tools to run a 9kb application a very robust solution.
What step am I missing for Qt deployment to Windows?
For specifics I have made this an open source project. You can see the release version of the application built in the bin/Win_x64 directory with all .dll files that I believe are necessary to run the application. If you copy that folder onto a Win x64 machine that doesn't have Qt installed then you should be able to reproduce my error.
Edit1:
I was asked to provide the list of files in my build/Release directory:
ArkCharacterSelector.exe
ArkCharacterSelector.res
CharacterManager.obj
Logger.obj
main.obj
moc_CharacterManager.cpp
moc_CharacterManager.obj
qrc_qml.cpp
qrc_qml.obj

Here are the files that are missing from master/bin/Win_x64:
bin/Win_x64
├── QtQuick (both dirs are from qt_base_dir/qml/QtQuick)
│ ├── Controls
│ └── Window.2
├── QtQuick.2 (both files are from qt_base_dir/qml/QtQuick.2)
│ ├── qmldir
│ └── qtquick2plugin.dll
│
│ (Those are only needed for QtWebKit builds)
├── icudt53.dll
├── icuin53.dll
└── icuuc53.dll
And these files can be removed:
bin/Win_x64
└── platform
├── qwindowsd.dll (debug dll)
└── qwindowsd.pdb (only needed for debugging the debug dll)
Happy deployment!
