Yes, the GUIs are quite efficient (IMO). One of the pathological cases 
that we had for awhile here at work was an application that built up its 
GUI dynamically (based on the contents of a configuration file) and for 
some cases was constructing thousands and thousands of widgets. Despite 
that unusually large size, it was still pretty responsive and so forth.

Widgets are very quick to construct and destroy, and don't seem to use 
that much memory. In C++-based FOX applications it's standard practice 
to just construct dialog boxes (e.g. file dialogs) as temporary objects, 
on the stack. We never used to do that in older Motif applications 
because it was so slow. As you noted, times (and memory constraints) 
have changed a lot since the 80's ;)
