Can I start my own mini-vegetable garden in a 12' X 5' space in front of my house? If so how should I start?

I have a nice space in front of my house that I would like to start planting vegetables and herbs in that I can use for cooking. I have never worked in or grown a garden before so I was wondering if some experienced gardeners can help me by giving me some tips on how to start....Thanx!
