Here's something I did with DD a few years ago and people are still using them:
Get some inexpensive wood picture frames that are pre-painted. Take some craft glue and paint it on the frame, covering the entire wood portion on the front side (make sure you take the glass off first and the back. Sprinkle seed beads over the glue, like you would do with glitter and cover the entire area-you may need to press some of the beads into areas if the frame is bumpy. Set it aside to dry and then shake off the beads that didn't stick. If it's not as "blingy" as you like, add more glue and do another layer or just put more glue in areas you want.
It helps to do this in a pan, like the large tinfoil ones you buy at the store for baking, this contains the seed beads, so that you can resuse the ones that didn't stick. You may also need to knock off some of the beads if they get in the area where the glass goes.
