Nothing in gtk+ will happen on its own ... you always have to have a
thread running the GUI.

I think the simplest solution would be to fork the process in the
background and start a timeout which fires a few times a second. In
the timeout, you should update the progress bar and poll the child to
see if it's finished.

There are more elaborate schemes with running the child as a separate
thread and using various IPC things to check progress and pick up
return values, but they are quite a bit more complicated.
