This probably answers most of my questions.  Obviously wxWidgets
is a C++ program which would call the C grass libraries.  I was
confused by the relationship of GTK+ and wxWidgets on Linux. 
wxWidgets "sits on top of GTK+" to use GTK+ as the native GUI
on Linux (only).  So based on Michael's answer above, wxWidgets
would make it easier to port GUI programs to other systems while 
doing away with the X11 requirement. This also avoids licensing
issues with Qt.

So ...  wxWidgets?
