In both cases I believe a BS_OWNERDRAW style button will do what you want
without having to handle mouse messages yourself in the first case or
having to build a complete custom control in the second (which, actually,
is really the same thing).

The owner of the button responds to the WM_MEASUREITEM message to tell Windows
how big the button is and responds to WM_DRAWITEM messages to paint the
button -- you can do anything you wish to display the button, make it clear,
any color, put text in it, etc.
