Now that made me laugh. Not getting feedback generally means one of
1) Nobody cares you did it
2) Nobody understands what you did
3) You got it pretty right
Given the usefulness of being able to code up a cross-platform gui, and
that a lot of people know wx quite well, I suspect that in this case it
must be 3. :)

I think you may have misunderstood my idea. The GS implementation does
have all those issues, and wxErlang does solve them. What I'm actually
thinking of is a separate "facade" layer over the top of wxE that you
code to like you would code to like you code to GS, and it transforms
the calls into wxE calls.
The GS-style facade can then add all the extra control goodness of wxE
to the GS interface but would shield you from some (most?) of the labor.
That way you get the best of both worlds. Another way of looking at it
is an erlang-style XRC that is specified as a term and thus could be
read by file:consult and just junked into a xxx:create_tree call.
Given your answer - I guess this isn't being worked on, so I'll have a
bash at a POC as I get time.
