title: GWT-Button acting as hyperlink
body: <p>I am trying to create an "Open" button which will open a new website.</p>
  
  <p>Unfortunately, I don't understand how to create an event that opens a new website. 
  How can I register the Hyperlink widget to this ClickEvent :</p>
  
  <pre><code> Button button = new Button("Open");
   button.addClickHandler(new ClickHandler() {
    public void onClick(ClickEvent event) {  
            Hyperlink widget = new Hyperlink("Home Page", "Home");
  
               }
   });
   rootPanel.add(button, 568, 275);
  </code></pre>
  
  <p>thanks in advance !</p>
