You want to create what is called a "modal dialog widget".
When the user hits the OK button, collect the information
from the form and store it at a global pointer location. Then
destroy the widget, which releases the modal block (sometimes
just a command line block), allowing you to retrieve the
information from the pointer and return it to the user.

You can read Chapter 13 of my book for all the gritty
details, or just grab some example code off my web page
if you want to learn by doing. You could start with
the GetImage program, for example:
