title: NSButton with title in different columns
body: <p>I am doing a MacOs application and I would like to have a NSButton like this:</p>
  
  <pre><code>    --------------------------
      | text1            text2 |
      --------------------------
  </code></pre>
  
  <p>I have been thinking and I don't find a solution to have both labels in the same button.</p>
  
  <p>Any ideas?</p>
  
  <p>Thanks in advance</p>
