Japanese Calligraphy?!?

So I'm doing a project on Japanese calligraphy, and to be honest...I know nothing. I'm going to be writing the quote “I will write peace on your wings and you will fly all over the world” in Japanese calligraphy, so I googled things on how to translate the words into calligraphy...but nothing really came up. Is Japanese calligraphy the same letters/words as the Japanese alphabet? I don't even know! I'm SO confused! If someone could send me some links or translate the quote to calligraphy or just help me, it'd be greatly appreciated! Thanks so much if you help!
