Help on 'Random' Pop Up windows

For anyone that could be of assistance, I am developing a simulation game, which throughout majority of the game the player would be hit with an unexpected pop up display. I have been researching endlessly on how to implement this. Is there a way without coding I could make this happen for those who are aware on how to make that work, or would coding be necessary? Thanks.

I don’t know anything about non-coding solutions, but you could look into Bolt.

With coding, it wouldn’t be very difficult. You’d have to learn the following pieces:

I started learning to code about a month ago, and I think it probably take me about half an hour to actually implement what you’re trying to do. Sorry I can’t be more helpful, but hopefully that points you in the right direction! Maybe someone more skilled than myself will pop in with actual code example for you.
