qmake -project

will generate you a boiler plate .pro file from the source, header, ui 
and resource files it finds in the directory.

I have not used the Qt plugin for VS for a while now but as far I 
remember the .pro file was just used by qmake to generate the MSVC 
project file. Not sure about the .user.pro file.

I don't have access to the Intel C++ compiler but it works well with the 
  MS compiler toolchain. However, it should just be a case of getting 
qmake to use the correct mkspec file so that the generated Makefiles 
call the icc tool rather than gcc or the MS compiler. The qt-creator 
list will be able to help you more with this I expect.

No problem. Good luck with the rest of your project.
