How to convert QtCreator project to Visual Studio project
Qt Creator / qmake can generate .vcproj files directly.
See this link
Put "TEMPLATE=vcapp" or "TEMPLATE=vclib" (as appropriate) in your .pro file and run qmake. That will generate a .vcproj file.
Edit: The link no longer worke, but I found an archive of it here
You can also use the qmake command to do this. Go to the project dir and type "qmake -tp vc".
