title: how to pause a program until a button is pressed
body: <p>I am using py2exe to make executable.
  I want to know how to pause the program until a button is pressed..  just like we do in C using <code>system("pause");</code></p>
  
  <p>As the program terminates automatically in windows, I need this tool.</p>
  
  <p><em>Is there anything better than py2exe which does similar work ?</em></p>
