How to hide File Edit Window and Help menus in a standalone

I guess the title says it all. I did some digging around the archives and found a recommendation to erase entries 329 and 330 in the MENU resource (using ResFork) to get rid of the File and Edit menus but even after I erased those, menus are still there. [menubar] object is another lead but it only allows adding and/or customizing a few entries. My hope is to get rid of everything, ideally even the About entry (although that one is lower priority as one could always create a custom one using aforesaid [menubar] object).
