As for the tint, try a soft mask, then airbrush some Tamiya smoke to the darkness you want. Seems like it would work for "privacy" glass as well.
For a greenish tint, might darken a clear green with some smoke, have to play with that.
The black edging could be done with either a sharpie or paint from the back side, with a hard mask.
I would dip in future first, just in case you don't like the result, might have a chance to clean off and save the window.
Try it on an old canopy or some clear styrene first.
Then you can glue it in with a clear parts adhesive (I like Pace Formula 560)
If you have any chrome, try one of the chrome pens that are out, they're great. .
