No. GWT can't do that.

Only classes that implement com.google.gwt.user.client.rpc.IsSerializable can be serialized and sent between the client and the server.

Widget's are not serializable, so it is better to send moel information and build the GUI on the client side.

If you want to use a custom component on the client, place it in the client directory.
