Yes, there are many opportunities for you as indie developer. first is app store ofcource, but please read first stories from iphonedevsdk.com/forum business section about 6 months development and more then $5000 spending and $100 profit at end. Second is flash games market, you can get up to $20k per game from sponsors if you are experienced game developer or about $500 if you are unknown. Third is android market, same as ios market but less money(successful game apps more ads oriented then apps in apple marketplace)

Forget about desktop. Its really hard make money if you are novice. Start from from mobile(cocos2d as already suggested is good helper in your way)
