I need to create a simple login requester (username & password). What's the best way to create that?

I originally assumed that I should use the requester.class, but that seems to be for predefined requesters only. There's no provision for adding custom GUI elements. Unless I've missed something...

So, are we supposed to use a struct Requester to build a custom one? Or use the window.class?

EDIT: I could be lazy and have separate requesters for the username and password, but that would create an extra step for the user. I'd rather have it all on one page.
