Geektool and NetNewsWire?

Hello all, I have my GeekTool set up to get my email and display it in a nice box on my desktop. I want to do the same thing with my RSS feeds that run through Google Reader. I use NetNewsWire to read and download my news stories. I want to have it set up so that it will display the stories on my desktop the same way my mail script works. Here’s my mail one:

set newline to ASCII character 10
set finalText to ""
tell application id "com.apple.mail"
	set unreadCount to (get unread count of inbox)
	if unreadCount > 0 then
		set theMessages to (messages of inbox whose read status is false)
		repeat with i from 1 to number of items in theMessages
			set thisMessage to item i of theMessages
			set fromMsg to (sender of thisMessage as string)
			set subjMsg to (subject of thisMessage as string)
			set finalText to finalText & i & ". " & fromMsg & newline & "    " & subjMsg & newline
		end repeat
	else
		set finalText to ""
	end if
end tell
finalText

So how can I change that to work with NetNewsWire? Or would I have to have a script that works directly with the Google Reader server?
