Just created this, and thought it worth preserving (not sure about lifespan of: http://pastie.org/981696):

public class ${argType}Event extends GwtEvent<${argType}Event.${argType}EventHandler> {

 public interface ${argType}EventHandler extends EventHandler {
  void on${argType}(${argType}Event ${argType});
 }
 
 public static final Type<${argType}EventHandler> TYPE = new Type<${argType}EventHandler>();
 private final String reason;

 public ${argType}Event(String reason) {
  this.reason = reason;
 }

 @Override
 protected void dispatch(${argType}EventHandler handler) {
  handler.on${argType}(this);
 }

 @Override
 public com.google.gwt.event.shared.GwtEvent.Type<${argType}EventHandler> getAssociatedType() {
  return TYPE;
 }

 public String getReason() {
  return reason;
 }
 
 public String toString() {
  return "${argType}Event:"+reason+":"+super.toString();
 }

}

GWT events are key to building a maintainable GUI I think, but it's a pain to cut'n'paste code for it.
