title: What is a good GUI programming language for an experienced PHP developer?
body: <p>I have been working with PHP for a while now and would like to learn some Windows desktop-based GUI applications.  Something similar to C# or Visual Basic would be nice, however I would like to learn a language that is open, similar to PHP. </p>
  
  <p>Please do not suggest anything that requires an expensive compiler or one that does not allow you to create stand-alone applications.</p>
