Window.confirm()?

We use this at the moment but there you can't change the buttons. In this confirm Dialog only "OK" or ´"Cancel" is avaible.

In that specific case, you'll want to Window.addClosingHandler and setMessage on the event.

We also have this handler added and it works well. Butt what do you mean with "setMessage"?

http://google-web-toolkit.googlecode.com/svn/javadoc/latest/com/google/gwt/user/client/Window.ClosingEvent.html#setMessage(java.lang.String)

"Set the message to a non-null value to present a confirmation dialog that asks the user whether or not she wishes to navigate away from the page." 

This is standard JS, the browser is left in control of how exactly it displays the message, but that's the only way to possibly prevent an "unload" of your app.
