Guestbook poster

I need a desktop app that will perform a simple google search, harvest a list of URLs, check to make sure that they are valid, and then be able to fill in forms. Specifically, I'm looking to fill in forms on a guestbook. It doesn't have to be particularly pretty, it just has to work. User would be able to put in any number of paragraphs, their name, email and website. The program would fill in the forms with this information automatically, choosing a random paragraph, at various intervals, and collect a list of URLs where the comment was posted successfully. I think that this seems like a pretty simple project, and I'm hoping to have it completed quickly and with a fairly low cost. I'll give more specific project details upon accepting your bid. You are free to use whatever programming language you want, so long as it runs on my Windows 7, 64-bit system. I will be the only one using this program, so it doesn't need a whole lot of extras.
