The good news is you probably won’t need a motor (if your motor runs) or any major parts which are costly. I had this just recently happen to my Alero and it is an easy and inexpensive fix. Remove the door panel and you will probably see a broken hard plastic clip (the weakest part of the system - a stupid idea) which holds the window in place. Order a new clip from rockauto.com (about $10. incl shipping) and replace it. A couple of hrs work and you’ll be back in bizz. The longest part of the job is removing the old clip. The dealer will charge you @ $250. to fix it, though, if you want to go that route. But, a little patience and you can do it. BTW, I didn’t see a cable like automatic windows used to have - a good move by Olds if my observation is correct.
