title: List of buttons in swing
body: <p>I would like to implement a list of interactive buttons using Swing. It is something similar as on the picture (from NetBeans UI designer):</p>
  
  <p><img src="https://i.stack.imgur.com/ChoF4.png" alt="enter image description here"></p>
  
  <p>You can drag and drop the items to a canvas, or single click on the item and then single click on the canvas. However, I don't know which swing components I should use. Are that JList or JButtons or something different?</p>
