Yes and no. It puts the empty frame in the notebook and labels it with 
"Module1" so that when you click the label, the frame is raised. Of 
course, not very interesting, because the frame is empty.

It adds an empty frame, as above.

blabla=BioDataForm() # whatever args it needs, maybe parent=nb

nb.add(blabla, text="Biodata")

PS: I suggest to change all Tk widgets to ttk widgets for optical 
reasons, but that's a side note.
