Popups possible in forms? If so Howto?

Fellow Informix'ers, Is it possible to get popups using forms. I have a screen in which there is one field that can only have values in an enumerated set. So when the cursor goes to that field, I want to throw a popup box, with the enumerated set and let the user make his selection. This value ten appears in the original field. How would I do this using forms. Yes, I can show the set in the comment line, and let the user enter the value, but a popup gives a better feel. Is this possible with forms? If not can it be simulated using multiple screens? Any and all responses appreciated.
