I'm trying to write a Cocoa application which allows me to see what buttons I'm pressing on my Wii Remote. I also want to be able to receive Nunchuck-data and set the LEDs. Does anyone know where I can start?
Oh, yes I did some searches, but I couldn't find anything useful.
Thanks in advance.

On episode 1 of MacBreak Dev, they show how to read from the Wii Remote and use it to drive a Quartz Composer composition. They use the WiiMote Control patch for Quartz Composer from Kineme. It sounds like that patch is based on the darwiin-remote project that Chuck links to in his answer.
This might let you do rapid prototyping of your application design, and you could even incorporate a working Quartz Composer composition into your Cocoa application when done.
There's an open-source project working on Wiimote support in OS X. They have a Cocoa-based library called WiRemoteFramework.
