How to create a custom alert

[Carol J. Elkins]

I'm looking for a way to create an alert message (Danger, Caution, 
etc.) that avoids having to make the whole thing a graphic. I have a 
manual with a zillion of these. They are rectangular with rounded 
corners; the width is constant and the height will vary according to 
message content. There is a red or yellow bar across the top 
containing the word DANGER or CAUTION (there is no symbol, just 
text). The area below that bar contains one of about 50 messages. 
They are all different. I would like to be able to add text to that 
area, while keeping the surrounding rectangular shape and its 
DANGER/CAUTION text constant. If it weren't for the rounded corners, 
I could do this easily with a two-celled table.

Does anyone know of a plug-in or workaround to easily handle these 
kind of alert messages? I'm using Frame 7 on Win2K.
