This site is pretty great for learning about runes:
A great book is Odin's Gateways by Katie Gerrard.
If you have an Android device, Galaxy Runes is a cool app you can use to help learn the runes as well.
Making runes is as easy or as difficult as you'd like it to be! It can be as simple as picking up some smooth rocks outside and drawing a rune onto each one with a sharpie.
To learn them well, I've taken to picking one out of a bag at random every week or so and carrying it around in my pocket to see what lessons I learn from it. I then take notes about it and when I feel like I've learned enough, I put it back and take out a new one. In my opinion, they're harder to learn than tarot since there's no visual queue or collective symbolism to help reinforce the interpretation of it. Once you learn them well, however, they have a very powerful and unique feeling to them. Have fun! :D
