I don't think you understand how Objective-J works (or GWT, or many of these other tools). You can use any existing JavaScript code in combination with Objective-J code. You can use any existing JavaScript code in combination with GWT too, if you do a little work. Writing an ECMAScript4 to JavaScript translator is really no different than writing an Objective-J to JavaScript one, except Objective-J runs in the browser, not on a python script running on a server. Objective-J runs natively in the browser, an impressive feat.
