A good starting point

[Wayne Stewart]

Hi,

I'm just starting to look at Obj-C & Cocoa/GnuStep.

I have lot's of mac's & so I can use XCode etc.  For my current uni 
subject I need to work on linux or windows - both foreign territory to 
me.

Does anyone have any recommendations for a good starting point for a 
novice?

i.e. FreeBSD, Linux (which type?), Windows (mingw or cygwin)

What I don't need is hassles setting up the system.

Thanks for the help,

Wayne
