For some definition of "simple" and "easy". The devil is in the details. 
Do you know glib? GTK? cairo?
The source code of a given version is here:

http://download.gimp.org/pub/gimp/v2.8/

The "live" repo is here:

https://github.com/GNOME/gimp

AFAIK there is no forum for people hacking Gimp at the C level. There is 
a "gimp-developer" mailing list, an IRC channel 
(irc://irc.gimp.org/#gimp), and a wiki at 
http://wiki.gimp.org/wiki/Main_Page

One last note:

- you can hack the "stable" 2.8 version, but all your changes will have 
to be moved to 2.10 when it comes out (and you'll want that one)
- you can hack the "development" 2.9 version (that will become 2.10 when 
fit for public use), but you can have problems with broken builds, bugs 
not in your code, etc
- and when you are done with either 2.8 or 2.9/2.10, you learn that the 
next version is 3.0 and is a essentially a major UI revamp.
