title: PYGTK uses more screen space than expected
body: <p>I am using PYGTK to program a very simple download manager, using both wGet and Python. Everything does well but it eats up a lot of screen space...
  My code:</p>
  
  <pre><code>#!/usr/bin/python
  import gtk
  import os
  def submitdownload(self):
      os.system("wget "+site.get_text() + " -P  "+ directory.get_text())
  main=gtk.Window()
  main.set_title("Simple Downloader with wGet")
  structure=gtk.Table(2, 6, True)
  label=gtk.Label("Simple downloader with wGet")
  sitedes=gtk.Label("Your download link:")
  site=gtk.Entry()
  submit=gtk.Button("Submit download")
  submit.connect("clicked", submitdownload)
  directorydes=gtk.Label("Save to: ")
  directory=gtk.Entry()
  description=gtk.Label("Please don't close the black box (terminal window) or the application will close automatically. It is needed for the download.")
  main.add(structure)
  structure.attach(label, 0, 2, 0, 1)
  structure.attach(sitedes, 0, 1, 1, 2)
  structure.attach(site, 1, 2, 1, 2)
  structure.attach(submit, 0, 2, 4, 5)
  structure.attach(directorydes, 0, 1, 2, 3)
  structure.attach(directory, 1, 2, 2, 3)
  structure.attach(description, 0, 2, 5, 6)
  main.connect("destroy", lambda w: gtk.main_quit())
  main.show_all()
  gtk.main()
  </code></pre>
  
  <p>It throws a lot of unused space at the right. How to fix that? It's very hard to close the application through the 'X' button.</p>
