few questions, FAQs ?

Ok here some dumb arse questions that i really cant get answers to.

1) briefly (and i mean like 2 sentances for each...) -- what is gtk, gtk+, gtkmm, gnomemm gtkmm, glademm and libglademm and their diffrences ?!.
- ive got a clue for most of these but it'd be nice to be sure on the *real* basics first.
 
2) im intrested in doing linux C++ gui's so im looking at gtkmm, is there a gtkmm forum or irc room ? i cant find one anywhere, and i dont really like mailing lists.
USENET maybe ?

3) i kind of have gtkmm working with anjuta IDE in linux, but is there a proper guide for setting the right flags and such for the compiler and preferences to anjuta on the net in regards to gtkmm ?

in regards to Q1) this might mean ive posted this to the wrong list and i actually wanted anouther list, but then thats just why the question needs an answer! :-)
