When I follow your directions I end up with the node-webkit clouds and an error that says:

Uncaught node.js Error

TypeError: undefined is not a function

The problem come from
gui.App.argv.length
if you use
gui.App.argv[0]
directly in the string, it works. But if you put something like :
var a = gui.App.argv.length;
before the querySelector, the error comes up.
