In the old days the old "Submit Your Site" button was at the bottom of all Google's search results pages. You didn't have to go through Webmaster Tools to use it. But apparently it's no longer available in that form.
At any rate, like I said earlier, it's not clear that Google will index a website that doesn't have any backlinks.
