RSS Docklet

Hello. Some days ago i saw an iphone aplication to read de feeds (can see the image) (WWW Link). Since that day i have been trying to create a docklet similar for my feeds in google reader. I really don't know if it's possible to do it. I'm using sysstats but, after many hours trying, i didn't make nothing. My line of work it's been to create something similar to gmail notifier, cause this docklet uses XMLMeter class too, but nothing. Can someone please help me? Has someone something looks like i am looking for?
Thanks in advance and sorry for my english.
