As mentioned, scraping Google violates their TOS. That said, that's probably not the answer you're looking for.
There's a PHP script available that does a perfect job of scraping Google: http://google-scraper.squabbel.com/ Just give it a keyword, # of results you want, and it'll return all the results for you. Just parse for the URLs returned, use urllib, or curl to extract the HTML source, and you're done.
You also really shouldn't attempt to scrape Google unless you got more than 100 proxy servers though. They'll easily ban your IP temporarily after a few attempts.
