I need some advice on what software I should be using to make a world map for starters.

I literally have no experience with any software such as Adobe Illustrator or photoshop, and if possible I'd like to do my work without having to shell out hundreds of dollars just so I can make a few maps.

Truthfully, I found this site, and immediately realized I was in over my head. There seems to be tons of intricacies and subtleties that I'm sure only only the most photoshop-savvy tech guys can put into practice, but I'm just looking to do something simple.

Any software suggestions?
