Can Unity Open a second game window?

I've tried to find some information on this, but my searches get messed up with some UI things instead of what I'm looking for. Am I able to have a program run in unity that would be able to open a second window . When I say this, I don't mean within the bounds of the window that opens when you start the unity program. I'm talking about a second window / windows form all together. Something you can have display outside the bounds of the starting program window. I'm working on a program and would love to be able to have the program, at run time, open up 2 windows instead of the normal 1. Any help on this would be greatly appreciated! :D
