title: Java GUI libraries
body: <p>I understand this question has been <a href="https://stackoverflow.com/questions/138722/which-gui-library-is-the-best-in-java">asked before</a>, but that was back in 2008, and things have changed. I tried looking for Swing, but the JFC is now outdated, and I can't seem to find Swing anywhere else.</p>
  
  <p>I'd like to know what the best up-to-date java GUI libraries are.</p>
