How to add menus and submenus to After Effect (AE)

Hi,

I am creating a small utility plug-in for After Effect, which has to launch some other applications like Photoshop, notepad etc.

For doing this, i would like to add menu like File, Edit etc. but it seems like that After Effect doesn't allow adding root menus, it allows only adding menus to some predefined locations (like AEGP_Menu_APPLE,   AEGP_Menu_FILE,   AEGP_Menu_EDIT ....). I am able to add menus to File menu or any other menu using AEGP_InsertMenuCommand(...). But, I am not able to find a way to add a menu and then submenu's to that menu.

I want to create a menu like this:

     File     Edit .....

     New

     .....

     .....

     My_launcher_Menu --> Photoshop

                                           Notepad

                                           One Note

Can any one tell me, how to add menu and submenu to that menu, or inserting root menus like File edit view etc....
