Mac user here. iMovie can do a lot and no degree required. I think FCP would require a degree and it costs a lot more.
Aperture doesn't require a degree. But as far as I know iPhoto will do a lot. Take one of the free classes that the Apple Stores offer if you can make it. That will give you an idea of the capability. http://www.apple.com/retail/workshops/#workshops_browser_gettingstarted
