yes, it is very possible.  gaim embeds several languages in its  
plugins.  i dug through the perl manual to figure out the attached  
example, but gaim has some code which may be illustrative (their perl  
support predates gtk2-perl, as far as i can tell, and has a  
mini-binding for the important bits of glib that gaim plugins need):

you will have to embed a perl/python interpreter in your plugins.

this is actually really easy with perl.  i figured it out in only a  
little while (granted i've been doing a lot of perlxs so i had an idea  
of i was doing) from the excellent tutorial in the perlembed manpage.   
the stuff i don't know really at all is the gtk module stuff.

attached is a simple example of how you'd do it.  i don't know how to  
tell gtk to load modules that aren't in the system gtk+ modules dir  
(e.g. /usr/lib/gtk-2.0/modules/) so you'll have to have root access to  
try it out (unless you installed gtk+ to a sandbox ;-).   the example  
uses a perl interpreter to load Gtk2 and create a new dialog 1 second  
after the app starts, without any changes to the app at all.  i didn't  
try to figure out how to communicate between the module and the app;  
that's your job.  :-)

i imagine that python would be very similar.

(by the way, you don't have to use the module with the included foo  
program, it also works with any gtk+ program (it was pretty cool to see  
it pop up over the gimp).)
