title: Best Java GUI editor
body: <p>I know there is nothing called the best Java IDE (Eclipse, NetBeans, etc.). Each one has its own speciality.</p>
  
  <p>But when it comes the GUI editor (visual editor) there are some interesting items out there; I would love to know which one is the most recommended.</p>
  
  <p>I am not asking for a full IDE, I am asking about any GUI editor or plugin for any IDE that allow me edit Java GUI (not necessarily Swing). I am also open for commercial alternatives it do not have to be free.</p>
  
  <p><a href="https://stackoverflow.com/questions/26458/ide-for-swing#26514">This question</a> is somehow close to my question (I didn't notice it before asking, but I hope anyone searching for similar things benefit from both questions).</p>
