title: Tooltip for GWT
body: <p>GWT does provide tooltip with something like: </p>
  
  <pre><code>Label label = new Label("test");
  label.setTitle("This is a tooltip");
  </code></pre>
  
  <p><strong>Is there a way to style such tooltips? Is there a library for GWT that supports this?</strong></p>
  
  <p>Edit: How do I set the time for the tooltip to appear?    </p>
