Most of this is covered -- and attacked -- in the literature, and in particular the literature of years and years ago. People have been caring about secure windowing for ages; the first reference off the top of my head is this 20-plus year-old paper about extending X, but I'm sure you can find older things if you try.
Most of the attacks are along the lines of tricking the users, or relying on them not to pay attention. Randomized titlebar colors seem like they will work about as well as secure pictures for anti-phishing for banks, i.e., not actually that well.
Also, you should look at Qubes, from the previous post, which is actually attempting to be a secure desktop OS.
