Gadget for GMail

Understand GMail gadgets and the Google Wave API? Need GMail gadget that adds a link with dynamic anchor text to GMail (i.e. similar to the Buzz link in GMail that advertises Buzz today). The link should have an href of [login to view URL] . By "dynamic anchor text" I mean the text says Wave (3) if there are (say) three unread Waves in your Google Wave inbox.?
