I doubt that this problem exists in OS X as they would have had to port it
from the Classic Mac OS.  In OS X everything from the top level API's
(Carbon and Cocoa) down is either new or is from NextSTEP.  For more on how
Mac OS X is built here are some references:

I strongly recommend at least the first two sections of "Inside Mac OS X:
System Overview".

In Cocoa you would create NSMenu and NSMenuItem objects and manage them
using NSApplication.

Yes.  On Mac OS X there is a new menu that sits between the Apple icon in
the upper left hand corner and the first shell menu (typically "File").
This is application specific and includes the "Services" submenu, "Quit",
"Hide", "About", etc...
