You're better off reading their marketing info, but I can shed
a little light on Sunrise product.
Sunrise software's product does include an interactive GUI
layout tool, that generates code. When I was aquainted with
them (about a year ago), the product was call EzX, and generated
C code for both Motif and OpenLook API's. Actually, it generated
code for their own library of widgets, which were internally
mapped to Motif/Openlook widgets. Their GUI layout/editing tool
was very good, when I saw it.
I recall that the Python product was to generate Python code for
Motif/OpenLook (again, really for their own library), but I never
saw it. Python's power and lack of compile/link steps makes it great
for rapid GUI development work, and this is what they are probably
leveraging. They were also talking informally about a Windows-NT
port, but I don't know if this ever took off.
