The Gtk+ main loop has no chance to run.

Therefore the labels have no chance to be redrawn, and if
the program execution took any nonnegligible time you
probably noticed the GUI was completely non-responsive.

You can use for instance g_spawn_async...() + some
non-blocking form of communication (non-blocking waitpid,
GIOChannels), whatever suits you, but in any case you have
to run the command asynchronously and return control to the
Gtk+ main loop to get a responsive GUI.  This was discussed
many times here, search the archives.
