su spawns a new (shell) process. This is a new Process, so its
completely separated from the process it have been called. After the
line system("su -") you program would be sleeping and the opened shell
would not get any new commands like the call to your init script.
Simple solution:
Just pop up a box saying that the user has to start /etc/init.d/net.ath0
start before using your program.

This does not help either since your box would ask the root passwort in
the user process. su instead spawns the new process before asksing the
passwort. This reduces the risk that the passwort gets keylogged.
In fact program would be a root passwort sniffer which has to be
rejected.

Well your problem isnt gtkmm or glade based. But read on :)
