Problem is, Field API and Form API are separate things. You can add form elements to custom forms created with Form API, and you can add fields to custom entities created with Field API, but you can't really cross the border. Well, you can wrap form element into a field, but not the other way around.

    Definitely true of core, but with a little sprinkle of ctools you can pull it off. It's not pretty but it works – Clive Jun 29 '13 at 23:35
