title: Select item in list, show text in text area
body: <p>I am working on a rough draft of a gui, looking at different options. I was hopping to use a <code>JList</code> to show text in a <code>JTextArea</code> based on what <em>item</em> is selected. You can see the <code>JList</code> on the left and the <code>JTextArea</code> in the center.</p>
  
  <p>Or is there a better way to do this? I am already using tabs that will be used for a broad category. I saw that the <code>CardLayout</code>, but don't quite like the look. Any tips?</p>
