Hi

I'm new to Cocoa and I'm trying to figure out how to create a simple 
popup which can be displayed from a command line tool or a background 
process. Ideally it would be something like NSAlert plus a text input 
field. I've been reading Apple's docs on windows, documents and the 
various controllers, and playing around with Interface Builder, but I 
think I'm missing something basic. Any pointers on where to begin 
would be appreciated.
