title: JavaFX: what is the best way to display a simple message?
body: <p>In my application I need to display a warning/info message, but I don't know a simple way to do that because there is no JOptionPane or similar component on JavaFX.</p>
  
  <p>There is a Popup class, but you have to set many parameters to get a decent layout/position/background color/etc for a simple message... So I want to know if there is a simple, already implemented component to display messages, maybe in a third party library if JavaFX does not offer anything decent.</p>
  
  <p>Thanks in advance for any help/hints.</p>
