title: Turning a command line app into a Cocoa GUI app on Mac OS X?
body: <p>Is there any tutorials or references, if such thing is possible, to make GUI applications out of command line apps?<br>
  What I mean is, having a command line app, wrap it into an app bundle and create a Cocoa GUI app that would have a simple interface to execute the command line app with its flags and parameters.</p>
