how I can use DWT into the javascript of my Zimlet?

I saw the source code of yflickr Zimlet (because what i want to do is similar), and I saw that it use DWT construct (In particular DWTTabViewPage).

Where I can find some documentation about how use DWT?

Another Question:
I need to create an interactive table in Zimbra, the data are loaded from an external repository, and the user of Zimbra can select one of them. It's possible?
