My experience based on Qt 5.0.2

• read ReadME file to download perl, python and ruby. Make sure the executable path in in PATH env variable.
• OpenGL requirement: DirectX SDK The 6/7/2010 version is about 572MB. This will be installed to C:\Program Files (x86)\Microsoft DirectX SDK(June 2010) directory.
• modify mkspecs by searching qmake.conf. It was found in C:\Qt\qt-everwhere-opensource-src-5.0.2\qtbase\mkspecs\win32-msvc2010
• configure -static -release -platform win32-msvc2010 -opengl desktop

Basic

• Frame (seems to be the same as 'Dock' in Qt's language)
• Dock window/Dock Widget http://qt-project.org/doc/qt-4.8/mainwindows-dockwidgets.html
