title: How do I compile a PyQt script (.py) to a single standalone executable file for windows (.exe) and/or linux?
body: <p>I started to fiddle with PyQt, and made a "beautiful" script from the pyqt whitepaper example app (<a href="http://pastebin.com/NZnpxv2F" rel="noreferrer">pastebin</a>)</p>
  
  <p>It works perfectly in Windows and Linux (with qt environment already installed on both).</p>
  
  <p>Now my question is: Since I am trying to use Qt because it is compiled (at least pure old C++ based Qt), how can I compile some .exe file to run it on Windows, or a standalone executable for Linux.</p>
  
  <p>The point is that I want the program to be compiled, because of speed and portability, instead of interpreted from source, which would require a previous setup on any machine. One of the goals, for example, is sending small gui scripts via email to coworkers who are not programmers at all.</p>
