I have a problem!

I need some help. I just can't for the life of me figure out how to put any window treatments on this wall. I would love to make long tab topped curtains, but I don't know if they would work. I also don't know how just toppers would work either.
There are several problems with the wall:
1. There is just to much stuff on one wall.
2. The door.
3. There isn't much room between the wall and the window.
4. There isn't much room between the mantel and the window and the door.
Take a look at my picture (please ignore the mess) and if you have any advise I would appreciate it.
