I think you can find most of the info here :
Google Maps API - Google Code
I've tried to do something similar for Youtube, but sadly it's not easy
I could query but i had to convert the xml data to usable data,
I need to retry now that Agraham created the xml lib, this should help.
Since you need to show the actual Google data, maybe you can use the webBrowser.dll to show the info you want..
