End-User Authored Desktop Widgets

In order for Edgy to showcase desktop sizzle and configurability, it would be very good if end-users could easily author (and publish) their own custom desktop widgets (and panel applets).

It would help if they were able to leverage entry-level skills in HTML and Javascript to do so, with Python being a 'next-level' option.

The main pieces to make this a reality are:

1) a framework

2) easy publishing

3) easy installation

Optionally, a simple authoring environment would be nice, but nothing more complex than gedit should actually be necessary.

A collection of basic UI graphics under a CC license would also be very nice.
