How to make a close button like that of Windows

[EricsonJ]

I have created a form-like control in my program, but met some difficulties in creating the close button. If I use the Graphic Command, there is a gotfocus rectangle in the button if I press down it. If I use a toolbar, I cannot make the edge of the toolbar invisible(Coolbar can do this, but the problem in this case is that when the mouse moves over it, the edge of the toolbar appears again) .
