Not to flame you, but if you want to have menu bars attached to windows, why don't you stick up with Windows instead?
Apple has had the menu bar at the top, detached from the app window, since the Lisa and the Mac System 1, for two reasons: to save screen space, and to take advantage of Fitt's Law... Unless you work with a 60'' screen or something along those lines, you'll still be better off with Fitt's Law for the menu bar... Windows only takes advantage of it on the Start button, and on the close button and the app icon menu on maximized windows...
At first, I preferred the menus on top of the window as well. Now, I could never go back - I love the menubar!!!
