We think about adopting GWT. So, we have to make some architectural choices and we look at available candidate solutions.

First we understand :
- Ext-Gwt is a wrapper for javascript library ExtJs
- SmartGwt is a wrapper for javascript library SmartClient
- Gwt-Ext is a wrapper for old version of javascript library ExtJs (not an option for us)

But secondly, we read that Sencha also produce GXT which is not a GWT wrapper for javascript library but a GWT extension from Sencha company. Ok, nice, but unfortunately GXT doesn't appear in Sencha product list.

So we are in doubt. GXT is an other name for Ext-Gwt, an other product, or nothing at all ?
