Gravity Forms customization and Pro Sites

Hi!

I know Gravity Forms is not your plugin, but one of your supporters recommended it for me and it turned out working great. I want the form to look like the one with the orange button, and the red button is how the one i have created is looking (it's danish).

I want the text boxes to be longer, still responsive, and i do not want the password confirmation! If i has to be there i want it to be on the next line.

Also, is it possible to find a complete Pro Sites guide? I want to use it, but have some troubles.
