Dynamically Creating a Page

I have a site with a bunch of articles stored in a database. Users can submit articles, and a brief description of each article shows up on the front page. I want each article to have its own page.
Say a user submits an article called "I Lost my Hat", you could read that article and all comments on it by going to www.mywebsite.com/I_Lost_my_Hat
Is there any easy way to do this?
