Curtain Rods for Wall to Wall Windows, HELP!!!? - double rod curtain hardware

Hello everyone,
I have to find curtain rods from one of my walls. Basically, the whole wall, a window (sliding glass doors is). In other words, you can not mount curtain rods, using conventional equipment because there are not drywall and the window sum. Who knows what kind of curtain rod I wouuld? Preferably I would like to make a double cash.

Thank you!
