Answer 2

Also have a look at cocos2d which i think may make it easier to do something like this if they have to constantly be moving.

cocos2d is a game platform which has physics etc but also i believe has support for buttons so it should not be hard to achieve something like this. Check out the cocos2d website and documentation.
