after finding that its too hard to write GUI applications with WIN32API today im going to learn Qt. so I installed qt as follows.
first I installed VS 2010 express. its OK.
then downloaded Qt libraries 4.8.3 for Windows (VS 2010, 235 MB) from http://qt-project.org/downloads and installed it as a normal software. (in C:\Qt\4.8.3) it automatically installed assistant, designer … ect.
then downloaded Qt Creator 2.6.0 for Windows (51 MB) from http://qt-project.org/downloads and installed it also as a normal program.
now in qt creater when I try to creat a Qt project it says that no valide kits found.
here are some screenshots of the issue im facing.



what should I do now to start qt. please I need someones help to procced.
You don’t need QtCreator AND visual studio.
QtCreator is Qt’s own IDE and uses g++/mingw as the compiler (included in the download).
Qt includes QtDesigner – the graphical UI designer that you can use with visual studio or QtCreator.
If you want to use VS, install the qt-vs-addin and download the VS builds of the Qt libs.
If you want to use QtCreator, download the mingw builds of Qt.
Or in both cases you can download the source and build it from scratch using wither QtCreator or VS.
edit: You can make QtCreator use the VS compiler backend – in which case you should download the VS build of Qt. Personally I have never done this – if you are using VS then you may as well use the VS ide.
edit2: The free express version of VS can’t use plugins – so its a bit of pain to use with Qt. In this case you should probably use QtCreator.
