[gtkmm] Probably a stupid Gtk+ question

[Carl Nygard <cjnygard fast net>]

Like I said, this is probably stupid.  I've had this question rattling
around in my skull for a while, and instead of actually researching it,
I'm taking the easy way out and just asking:

If Gtk+ is built on an object model, why did those folks go to such
(rumored to be) herculean lengths to build one in C, instead of just
using C++?  I can think perhaps language bindings had something to do,
but the only problem that jumps out there would be scheme/lisp binding. 
Perl/python/ruby are already OO themselves.  

I'm sure theres a good reason, just curious... and not looking to start
a language war.
