There's a programming forum where you can post this stuff.
In fact, I recently saw a thread where a group of interested programming newb were forming a group. You could check that out, maybe:

There are dozens of directions you could go in, but since this is a Mac board, you might consider Objective-C/Cocoa programming on Mac OS. All the developer tools you need come with OS X.
Look here:

First you'll want to learn Objective-C:

Then you'll want to start learning Cocoa:
http://developer.apple.com/document...ial/index.html#//apple_ref/doc/uid/TP40000863
There are also some good books. One I think is great for new programmers learning Objective-C is:

Good luck
