Need help writting code from dynamic menu

Heres what I am trying to do:

I have a form that has a main menu (mm) a submenu (mnu) whos text property is "Test", two text boxes (txtA, txtB) and a button (cmdGo)

I also have a class (cls) whos properties are A, and B (string values)

When the user clicks the button, a new class is created and the properties A and B are set to txtA and txtB respectivly.

Now the hard part...

How can I write code that when the user clicks the button, the new class is created, a new menu item appears under mnu whose text property is the value of the class's A property, and when clicked, it will pop up with a msgbox displaying the classes B propery?
