None of this stuff can be right. I'd strip it all out, go back to 
a simple approach and tell us what doesn't work with that. A small
standalone compilable test case might help.

In almost all cases, you just need to tell GTK+ what you want it
to do (change the text in a label, say), and GTK+ will figure out
resizing and repainting it needs to do it.
