I've got a very simple project in mind: it's a menubar app that shows an icon in the menubar in one of two different states, depending on which way a system prefs switch is set, and gives you the option to choose a key combo to trigger that switch.

Where would you start if you were building something like this for OSX? I'm pretty much still walking in the door of writing apps for OSX, so the simpler the better. I'm sure I could use Xcode to do this, but every time I launch it I get agoraphobia - so many options... agh!
