title: How to make Multi-Pane GUI in WPF or C#?
body: <p>I have seen this user interface in some screen shots of some RSS Readers.  It is a multi-pane user interface.  THere are three panels or "panes" to the window, in other words, the window is divided into three parts and the user is able to mouse over the division and click on the seperation bar and resize the section.</p>
  
  <p>How is this sort of GUI developed in C#?</p>
