I have added a new wrapper based on your example and updated Demo 31 to show you how to use the wrapper.

i.e.

from spam import OpenDialog
    def testOpenDialog(self):
        print("OpenDialog test:")
        open_dialog = CreateComponent("TOpenDialog", None)
        if open_dialog.Execute():
            print("FileName:", open_dialog.FileName)
        open_dialog.Free()
