   I think that programmer should write thier own widgets when
a widget that serves a specific purpose is called for, for instance;
a keypad widget or a GtkVScale that responds nicely on a touchscreen.

I think you should use libglade... and the gtk builder in future versions
to build your ui from an xml description, it will drasticly reduce your 
program's
complexity and as an added advantage; it will allow you to change your UI
without recompiling your code. You're own invented widgets can also be
loaded by libglade... and easily plugged into glade3 or gazpacho designers.
