The commercial version is 100% compatible with the open source version, so "porting" is just a recompile of your program.
Your "personal feeling" is mine also. I use the commercial version of QT at work and on occasions I email the source home to play with the code at night on the GPL version of QT. When I am done I email the results back to work and I have no trouble with the process.
