How to add a colored square in the titlebar through api

Sometimes it's neccessary to add a Caption in the titlebar to give extra information to the user of your application. The attached file does this, and makes sure the window got redrawn when windows triggers arive.
As you can see, many instances of msgblst32 are added on this window. The goal is to make it more the controlling window which always catches the events on the underlaying session applications. As every window needs its own ocx, I provided 40 instances which are hopefully enough to maintain every window.
