If you look at the WidgetWrap code the I provided for X11R3 (the
predicessor to the varargs style interface now used in X11R4),
there is a demo program that does precisely this.  It's not geared
towards motif -- it uses athena widgets by default.  However, it
is very simple to generalize this for Motif or any arbitrary widget
set.  I get requests for this all the time, so rather than ask me
for it, please get it out of the old R3 distribution (in contrib/widgets)
or query your local s-xources archive site (or uunet).  It's volume 3
issue 76.  It's also in the WidgetWrap directory in "contrib" on expo.
