title: Writing GUI frontend for commandline application in Mac OS X
body: <p>I am wondering if there is a source of information on how to develop a GUI frontend application for a commandline one in Mac OS X in, but not necessarily, Xcode?</p>
  
  <p>Specifically, I would love a GUI frontend that lets me specify arguments to pass to the commandline program.</p>
  
  <p>Thank you very much.</p>
