How can I create a pop up window?

I am working with a LOT of configurations lately, and I would like to create a pop up window or notes or something to let any user know that he is working on a part with configurations, ideally this will work like this: You open a part and at the same moment that you can see the part in the screen a pop up window will appear saying: "You are working on a part with configurations, please review them for more details". Is there anyway to do this other than creating a macros?
