It is time to consider dropping the dependence
and development in X11 in favor of more modern
cross-platform GUI environments. Of course
Java is one that comes to mind. Python with
appropriate add-ons is yet another.
As Ernest said, CSS is an activity emerging on this front.

Fedora Core to drop openmotif [Distributions] Posted Aug 31, 2006
16:13 UTC (Thu) by corbet
It's official: Fedora Core 6 will not include the openmotif
library, which has a non-free license. The library will be removed
prior to the October 2 development freeze. As a result, a number of
packages using openmotif (including cmucl, ddd, nedit, and xpdf)
will break; they, too, will be removed if they cannot be shifted
over to lesstif in the next month.

This won't prevent OpenMotif from being installed on FC6 machines,
but it will involve extra work. FC6 will include LesTif, but that's
not 100% compatible with the original, and I know we had problems
with it before OpenMotif came out.
I would not recommend using LessTif for anything that should work
reliably and emphatically not as a replacement in EPICS applications
that are based on (Open)Motif.
One example: my favourite text editor 'NEdit', an otherwise extremely
stable and actively maintained program, is almost completely unusable
with LessTif. The developers insist that this is not their fault:
LessTif simply remains bug ridden, despite several reports, some of
them _years_ ago. It just seems that LessTif doesn't attract enough
active developers to really get rid of these problems.
OTOH, I have to warn that switching from Motif to a completely different
GUI library, such as GTK or Qt (as suggested by Kay), or possibly to
some portable library such as wxWindows, in practice means a complete
rewrite, at least of the GUI part of the app. This is a _considerable_
effort. New applications are, of course, a different matter, as is the
case where a rewrite is planned anyway.
The EPICS EXTENSIONS have lasted a very long time and we all enjoy them.
So, what is next? Yes, maybe a re-write is in order for the future
longevity and maintainability. :)
The activity from the Control Systems Studio team has gotten a start
down the path.
Just my 2c.
