Good thing, I found out about GIMP. It's a free graphic design software, simple enough to use. Worthwhile learning, especially there are tons of videos you can research find online especially on Youtube.
For a start, I learned to do basic editing with pictures, integrating a little bit of special effects. Check out this really useful GIMP basic video at http://www.youtube.com/watch?v=vVy_EDDe_-0&feature=fvw.

I'm sure this might look a little bit very basic for a graphic design, but otherwise, baby steps are still the way to go to mastery. "To get the stars, you take on step at a time."
