Synchronize GTK main loop with a Motif window

[Andrea Maiolo <amaiolo ilm com>]

Hello Folks,
I'm new to GTK programing so be nice with me if I'm asking something 
silly ;-)

Is there a way to synchronize a Motif window with the GTK main look the 
same way I could do in Qt using QMotif ( 
http://doc.trolltech.com/3.3/qmotif.html )?

I have a couple of new thick books at my desk and I just finished to 
search the net with no result.

Thank you in advance.
