Programming... Where to begin?


I was wondering whether anyone might be able to suggest the best place to start with regard to programming for Mac... I don't have any previous programming experience however I am very interested in programming for Mac OS X. Do I need to learn C or Java or something else before using the developer toolkit that came bundled with my G4 Cube and Titanium Powerbook? Thanks in advance!
I'm pretty new to developing too, but I do know that it's a MUST to know java or C++. If you can, learn both. Once you learn the basics of one of these languages (without OS integration) then you can start using your Developing Kit with all the Mac enhancements. There are plenty of tutorials on the web, I suggest trying CodewarriorU . It's VERY professional, and FREE!!!!
