I agree that TeleUSE is a good GUI development system, and the D language is
very well suited for the problem area (I developed LOTS of lines of D a few
years back).  One thing you overlook - D is a 4GL which is converted into
native C X Window System code.  Machine generated, ugly, but if you want to 
muck about in it, you can capture it and hack to your heart's content.  For 
those of us living under an Ada mandate, Telesoft/Alsys/Thomson has a version 
that outputs Ada from the D compiler, and not C/C++.   I've even heard of 
some brave fools who've taken the machine-generated code from a prototype 
and worked that into shape for their full-up project.
