C++ Class Generator, or CPPCG, is a tool -currently in Beta phase- which allows you to create C++ clases in a very simple and quick way, instead of wasting your time copying the common code again and again. Obviously CPPCG doesn't make miracles since it won't create everything for you (the hard work is yours), but it will make you gain some time, so specially if you are a beginner you may find it usefull.
CPPCG is programmed using C++ and Qt4 (a cross-platform framework), it's open source ant it's under the GNU General Public License (GPL), which means among other things that you are free to download the source code and tinker with it all you want. It is available for Windows, Mac OS X and Linux (see notes on the Downloads section). You can take a look at the screenshots of the right sidebar.
