Steve,
Scan the photo, open the scanned image file with your software and start experimenting. Some photo editing programs have good introductory tutorials. Some automate the process (more or less). For example, my Adobe Photo Deluxe has a button marked "Get & Fix Photo." All the programs have help available through a structured menu system.
If you are interested in a new hobby, teach yourself. Might take a while. Photo editing programs tend to be less intuitive than a world processor for example. However, photo editing can be a lot of fun. I enjoy designing labels for homemade CDs. If you want good results immediately, get someone else to do it or have someone teach you.
