Idea feedback for newbie

I have been messing around with Applescript for a couple of months and I have been trying to find a way to send info to a couple of fields (login info) on a webpage and submit the info. The applescript app would then periodically check the web site and notify me of updates. Upon update I could send a play (media file) command. Basically a nice front end to a webpage service.

I cannot seem to access webpage contents as easily as I thought through AS

Is this possible or do I need to stick to figuring this out in javascript or perl?
