title: JMenuItem delete "X" to the right of the text
body: <p>I have a JMenuItem which I would like to be able to remove from the menu.</p>
  
  <pre><code>[ ] The Item      X
  [x] Selected Item X
  </code></pre>
  
  <p>I currently have the menu created with radio buttons so that as each item is selected, the others are deselected.</p>
  
  <p>I would like the "X" to the right of the menu, to remove the item from the menu itself.</p>
