 Hello,

 I think you have the right idea with transitioning to wx API
incrementally, as it worked well for me on several past projects where I
migrated code using MFC to wx, but I've never done it for Motif and, to be
completely honest, I had to fix a couple of things inside wx itself to make
migrating from MFC less unpleasant, so it's not impossible that you run
into some problems with doing it for Motif too.

 In theory, yes, as you can get Motif widgets it uses from a wxWindow, so
you could start by just introducing wxApp, running wx event loop, and then
create wxTopLevelWindow (e.g. a wxFrame) and keep the existing Motif code
otherwise unchanged. But, again, in practice I haven't tried doing it.

 Good luck, you will probably (certainly?) need it!
