This is bad. You're basically initializing the same object twice. ;-)

Just plain [window show] is correct.

Might want to do 
	[hello free]

Since you won't really need to access your application object from
anywhere, else, even
	[[[[Hello alloc] initApp:&argc :&argv] run] free];

would work, although that's stepping dangerously close to lisp ;-)

Hmm, I've never seen that problem before. If you can compile regular Gtk+
apps, and you can compile ObjC apps, there shouldn't be any problem.

'nm' around and let me know where exactly those symbols are being used...
