Wrong. GPL does not prevent you from developing commercial softwarre. You just have to release your source under GPL.
GPL is free as in freedom. It doesn't have to be free as in "free beer". There are customers paying for software relesed under GPL. They just needed it and didn't care if others used it too.

As already said, if you use parts of GPL code in your (non private) project, the whole project has to be GPL.

GPL does not cover commercial vs. non-commertial. Just freedom vs. proprietary.
