As in a game maker do you mean to add in into a game?
If so then depending on the game and how kind the person is you might be able to get a plug in say for, I dont know errr, GTA???
If you want to make a game them you really need a engine, micorsoft do a decent one XNA, although you can make your own or use someones using C# or C++, (C# on MSDN has some great tuts agoing over the real basics)..
