Look at JavaScriptObject:
http://code.google.com/docreader/#p=google-web-toolkit-doc-1-5&s=google-web-toolkit-doc-1-5&t=DevGuideOverlayTypes
In particular you might write something like this:
public class Car extends JavaScriptObject {
public static final native Car newCar() /*-{ return new Car(); }-*/;
protected Car() {
}
public final native void drive(String from, String to)/*-{
this.drive(from, to); }-*/
}
