User Interfaces for multiple platforms

[David Angulo]

We are looking for a user interface package to handle pull down windows,
menus, textual windows, etc. that is available on a number of platforms
(OS/2, X-terminals, VAX/VMS, and perhaps UNIX) with a common programming
interface.  Preferably supporting mouse use on those platforms where
available.  We would like it to be in objects usable from c++ but doubt
that we will find that so ANY package is fine (we can write our own
classes around them).  Does anyone know of any such thing?  The closest
thing that I'm aware of is Glockenspiel's CommonView which evidently isn't
very good.  Please e-mail responses and I will post results if anyone
is interested.
