Qt Creator is not a compiler, but is an IDE.  It can work with different 
compilers and different Qt installations.  You just need to match your compiler 
(e.g. mingw or MSVC) with the Qt installation you want to use.

CMake will let you choose the following that should with Qt Creator:
CodeBlocks - MinGW Makefiles
CodeBlocks - NMake Makefiles
CodeBlocks - Unix Makefiles

No need to do that (in fact is already is built with Visual Studio, but comes 
with a mingw built Qt installation).

Hopefully you already installed the mingw compiler as part of the Qt SDK 
installation.
Try this:
run cmake-gui
generate your project with the "CodeBlocks - MinGW Makefiles" and choose 
C:\QtSDK\Desktop\Qt\4.7.3\mingw\bin\qmake.exe for QT_QMAKE_EXECUTABLE.
cmake-gui will give you more interactivity than Qt Creator's cmake dialog if 
you do the initial project set up there.

Once that is working, open Qt Creator and do File -> Open and choose the 
CMakeLists.txt file for your project.  In the next dialog, fill in the build 
directory where you previously told cmake-gui to generate the project.
Hit the "Run CMake" and finish button in that dialog.
