I just saw this plugin thats supposed to do it automatically – http://wordpress.org/plugins/genesis-translations/ I haven’t tested it yet, but give it a try and let me know if it works. Otherwise you would have to manually translate it. You could do a Google search for “How to translate a Genesis theme”
Also, since this is a German site, you could ask a well known Genesis Developer named David Decker – https://twitter.com/deckerweb (<– Twitter link, which also has his website you can contact him at) He is pretty good at translating, and may already have it ready.
I create awesome sites for awesome people! Contact me if interested – ericsanchez1585@gmail.com
