The qooxdoo Web Toolkit is like “qooxdoo for Java”: Write your qooxdoo application in Java, and QWT will translate the client part to JavaScript. QWT is quite similar to Google Web Toolkit, but has the qooxdoo widget set.

The typical “Hello World” application looks like this:

import qx.application.Gui;
import qx.ui.basic.Label;
 
public class Application extends Gui {
    public void main() {
        super.main();
        new Label("Hello, world!").addToDocument();
    }
}
