Depends on how low you wanna go with it. Git is a command line tool, but there are some nice GUI tools out there. If you’re on Windows/Mac there is http://www.sourcetreeapp.com/ and if you’re on Linux there is SmartGit (their site is 404ing for me right now).
The creators of Source Tree (and BitBucket, a great free online private repo) put out probably the best Git tutorial series I’ve seen. https://www.atlassian.com/git/tutorials/ I think it’s mostly command line based, but if you go through the Getting Started tutorial, you’ll get a good feel for it.
Git, and source control in general, can be intimidating at first. But you need it if you work with code and if you stick with it you’ll figure out it’s really not that complicated or hard, just a lot of things you can do with it.
There are also other forms of source control like Mercurial, SVN, Perforce, etc. Git is the most popular right now and for good reasons. It’s very powerful and very easy to use once you get going.
