It should be noted that there's a difference between customising the existing title bar on a form, which can be done, and removing it and replacing it with a fake one. If you customise the real title bar then any windows functions that rely on the real title bar will work. There's no need to worry about implementing your own drag and drop or creating your own buttons. You may have seen that Office 2007 apps sometimes momentarily revert to the standard title bar under heavy system load. That's because the system hasn't had time to redraw the title bar using the app's specs, so the standard one gets drawn instead.
