Simple Program to search for a keyword in Google and then click on a specific URL

I would like a pretty simple program made. The program simply needs to search in google for a given keyword, and then click on a specific URL when it is found in the results. It may need to go several pages deep to find the right URL. But when it finds the URL it should click on it. And once on the page it should have the ability to then click on a specific link on that page. The program should then wait a set amount of time and then go back to google and do it all over again. The ability to use a list of proxies or change the User Agent would be helpful as well. The interface should allow me to add the keyword and url combos, load any proxies, specify the link to be clicked on and choose how long to stay on the page before clicking on the link. You are free to design it in any language you prefer or think is best, and can make it to run from a PC desktop or even be a script I upload to one of my sites. The only thing I require is that you document the code properly, so the program/script can be modified or troubleshooted later by other programers if needed.
