This:

          self.inputs['Last name'] = cc.LabelInput(
              ContactNameInput, 'lname',
              input_class = ttk.Entry,
              input_var = tk.StringVar()
              )

should be this:

          self.inputs['Last name'] = cc.LabelInput(
              self, 'lname',
              input_class = ttk.Entry,
              input_var = tk.StringVar()
              )

Also, this:

          self.inputs['First name'] = cc.LabelInput(
              ContactNameInput, 'fname',
              input_class = ttk.Entry,
              input_var = tk.StringVar()
              )

should be this:

          self.inputs['First name'] = cc.LabelInput(
              self, 'fname',
              input_class = ttk.Entry,
              input_var = tk.StringVar()
              )
