There are a number of books that walk you though, step by step, in creating a small game so that you can get the idea such as "How To Program a Game in 24 Hours" or http://safari.samspublishing.com/067232461X. Having worked in the software games industry for nearly 10 years, I have seen many things happen including a "pet project" of one of our programmers that got published.
