Pop-Up Windows in RPG Maker MV

So awhile back I posted a thread for RPG Maker VX Ace asking for the same thing (Posted at bottom of thread) and was asking about making pop-up windows that appear as separate windows outside of the game itself. I was told that there was a system built into RPG Maker VX Ace already, which made creating the windows easy. Is there a system like this in MV? If not, how would I go about obtaining a plugin that would allow me to do this?

If you need a reference point for what I'm looking for, check out the post I mentioned.

I think the JavaScript equivalent of RGSS3's msgbox is alert:
Just put it in a script call and it should work fine. =)

if your game is a windows application, using nwjs there will very likely be a way to spawn a process.

Also, this would have been possible in ace.. I wrote a cheat system that opened a notepad and wrote 'cheating is bad m'kay' hundreds of times, and then it opened 99 times.

This is great and all, and maybe I'm just being too picky, but I think it's a little jarring for the Pop-up window to be completely different looking compared to the actual game. Is there a way to make a pop-up window similar to the one in VX Ace which looked like so:

Again, maybe I'm just being too picky but if there is a way to make a pop-up window that looks more like this (and I realize that this probably needs a plugin to acheive) I would appreciate it! However, if not, I will use the alert function instead
I assume by this you mean the NW.js (Not really familiar with this tool just looked it up after I saw this reply), and the issue with that would be the fact that it is windows only, considering that I would like to be able to port my games to Mac (but not IOS or Android if there is a workaround for mac but not those two) for obvious reasons.

Thanks for the replies nonetheless!
