Google Chrome Extensions: Popup window like Firebug Lite?

I want to pop open a little window/frame like Firebug Lite does when you click the browser action. I know how to detect the click event in the background page, but how do I produce a an embedded window like that? Tha开发者_JAVA技巧t's not done with standard javascript is it?

Chrome API doesn't provide any tools for creating GUI elements, so everything needs to be done in pure javascript and css.

I have used Notifications once..its pretty cool ;) http://code.google.com/chrome/extensions/notifications.html

this will do the job , imo .
