I believe Google News (like a lot of Google stuff;-) is in a mixture of C++, Java, and Python, plus Javascript on the front-most part too -- but there's no reason you should use all or even any of these excellent languages (well, you will want Javascript if you need highly interactive user experience with your site, of course;-); just about any language makes it easy to do web crawling. For example, for a web crawler in PHP, see this tutorial!
