1.Are there any\ do you know of any Freeware\FOSS GWT Designers which enable developers to create U/I's using a drag-drop from a VB like IDE ?

I know about Instantiations GWT Designer but that is a commercial software and I know Googlipse which has Exlipse Integration for projects but not a visual U/I designer.

2. How easy is it to integrate external js libraries like Scriptaculous\Prototype\In-house,home-grown js file within a GWT app. Can it create any conflicts ?
The reason I ask is that over time,as we get more experienced with JS, its easier to figure out how to do something in JS rather than think in Java. I hope its easy to integrate GWT generated JS and developer generated JS.

3. If existing enterprise apps using GWT switch to using .NET, is there a possible upgrade path to switch an app using GWT components\widgets over to .NET ?

1. I am not aware of any freeware designers for GWT. IntelliJ the maker of Idea also has an IDE for building GWT guis.

2. GWT provides a feature called JSNI(Javascript Native Interface) which enables you to integrate JS libs into GWT Java code. You can call from Java classes into JS code and vice versa. It is very cool! You can certainly get conflicts depending on what you are integrating.

3. I am not aware of any way to convert GWT components over to .Net components.

If you're gonna buy things, buy this thing and I get a fat kickback:
