I need to build an app that controls GarageBand on OS X.

It's an app for iPhone that would control basic functions from OS X GarageBand like play, pause, etc. I don't know how to build this app, how can I communicate with OS X?. Some friends told me about bonjour, but I have no experience with it and I have no idea on how to use it to build this app and yes I've read the bonjour's page.

Can someone give me some direction?

Your best bet is CoreMidi

Garage Band speaks midi, and if your app sends midi signals either over USB or some other protocol (like Bonjour to a listening client app) you can interact with GarageBand this way.
