Answer 1

The answer to your question is Command.
http://google-web-toolkit.googlecode.com/svn/javadoc/2.3/com/google/gwt/user/client/Command.html.

When you add an item to the menubar (or to any of its children) you specify

 Command helloCmd = new Command() {
   public void execute() {
     Window.alert("Hello");
   }
 };
addItem("Hello", helloCmd);

or

menuItem.setCommand(helloCmd);

You could also execute the command independent of any menu items:

 helloCmd.execute();
