GTK x Motiff question

["asdfqwert zxcvv" <gtklist hotmail com>]

Hi folks...
I am a newbie at GTK+ and i am really interested in getting into it...
I have a project at my university that involves GUI programming, and i 
really would like to use GTK+ for it. The problem is that my orientator who 
is a old unixer, insist in using Motiff, his main argument is that Motif 
uses very less libs, so it gets a faster application. Can u PLZ help me with 
some arguments,if they exist, so i can keep working on GTK ?!
                                   Thanx a lot!
