You can do this really easily with PHP. There are a ton of free Google scraping scripts out there if you do a little search. Really, it all depends on how much scraping you plan on doing. Google will temporarily ban IP addresses that make a ton of searches one after another. If you're only looking to do the occasional scrape, most scraping scripts will be fine.
