tell application to display window from nib, like in applescript

a newbie question:

can you actually tell an application (like iTunes) to open a window, built in interfacebuilder?

i want to achieve the same effect that you get when you do something like this in applescript:

tell app “iTunes”
display dialog
end tell

so to speak, make a dialog appear in a targeted application.

?

jns

i guess i could work somehow like this:

on launched theObject
	show window 1 in front of window 1 of application "iTunes"
end launched

if it works at all.
