You could use the DoCmd method of the Application object to execute an evaluateable expression, but I think you might get into some enviromnent and scope problems if you are trying to call methods of objects that don't have direct references from the Application object.
I would suggest creating some of your classes as OLEPUBLIC and instantiating them directly as COM objects. You might want to give some details here about what you are trying to accomplish.
