title: Using two JPanels in one JFrame
body: <p>I'm attempting to create a program that allows the user to click a button to place something in the <code>JPanel</code> and allowing them to move this item around. I have already found a good layout to use to allow the moving components (see <a href="http://tips4java.wordpress.com/2011/10/23/drag-layout/" rel="noreferrer">this</a> link). However, I'm just curious the best way to create a layout like this? My hope is to have something like this:</p>

  <p>How can I accomplish this? Would I want to use two <code>JPanel</code>'s or something else?</p>
