Technique to create static URLs and web pages for Q&A, discussion forums?

I want to create a discussion forum on my Web Site. The title of the forum should become a static URL on my website domain address. This is very similar to how Stackover flow does it. Example : If my domain address is http://ift.tt/1NZhLuj, then for every question posted on the web site, I want to create a GET request like : http://ift.tt/1iAIrUF
How to create such URLs and their corresponding pages.
