title: Python GUI (glade) to display output of shell process
body: <p>I'm writing a python application that runs several subprocesses using subprocess.Popen objects.
  I have a glade GUI and want to display the output of these commands (running in subprocess.Popen) in the gui in real time.</p>
  
  <p>Can anyone suggest a way to do this? What glade object do I need to use and how to redirect the output?</p>
