I'd actually pick up php with one of the simple frameworks like Laravel (or even go frameworkless in the beginning). I think it's a bit more straightforward than picking up Node. Otherwise Rails is nice for beginners as well and has a big market in the U.S. Java/.NET aren't beginner friendly at all.
