what should i use to attach a window to my door, i was thinking of using rivets?

2 sided tape works great and looks good to.

2 sided tape or screws and bolts if it fits your disign.
some kits have tubing which attaches them both.

im not going to use two sided tape that is a bum way of doing it i think im going to use the stuff they use to attach car windows with ill probably find something good at home depot
