title: How to make JButton with transparent background and regular text?
body: <p>Is there a way to make a <code>JButton</code> which has a transparent fill(30% transparent) and a text which is not transparent?</p>
  
  <p>For now I discovered the following options:</p>
  
  <ol>
  <li>make both the button and the text transparent.</li>
  <li>make both of them not transparent.</li>
  </ol>
  
  <p>is there an option in between?</p>
