I have the same problem.  I have looked at Motif++, WWL, InterViews, GINA++,
and a few variations on the above.  I've also done a cursory examination
of Rogue Wave's View.h++.  I like View.h++'s abstractions best of all of the
toolkits I mentioned, but the resulting code looks little like Motif, and I
have little confidence that this software will catch on or otherwise result
in significant longevity for my code.  GINA++ allows you to write code which
looks a great deal like Motif and also makes interesting use of inheritance,
but the resulting code is almost too Motif-like, and is certainly not
significantly less verbose than equivalent C code.  InterViews looks
promising, but I haven't found a free version with Motif support, and I'm
not confident how widely InterViews with Motif support will be adopted,
and what (if any) specific Motif support will be available over time.  The
other libraries produce code which is less Motif-like, but which does not make
sufficient use of the features of C++ to simplify my coding task.

At this point, my inclination is to write my Motif manipulation routines in
C, and invoke those routines from my C++ code using simple abstractions suited
to my specific task.  Later, if OSF or some credible standards-setting body
comes up with a C++ interface to Motif, I will change to that.  It does me
no goo to write in C++ if my choice of interfaces leaves me with code which
leaves me tied to an abstraction which is not consistent with the industry
directions.  It's better to take a standard if inferior solution for now
than to go with a slgihtly superior approach which will leave me with both
useless code and useless skills a few years from now.  Views.h++ is the only
library I'd consider right now, but in our environment, we'd end up spending
nearly $5000 to use it, and I can't justify it when it's likely to cause
short-term productivity decreases as we learn the new abstraction, and is
unlikely to be a sufficiently long-lived solution for us to reap the benefits
at the high end of the J curve.
