This is possible using appearance dictionaries and forms; basically you need to 
define a form called formName and then use it as the normal appearance of an 
annotation.

eg (assuming we created a form with the display content) this will create and 
show the form and a link in the form, but not show anything when printed. If you 
don't need the clickable link don't do the linkURL bit.
