sure, everything will go into a "label_entry" function

It's similar to this:

def __label_entry (self, frame, text_label, width_label, width_entry, 
maxlen):
          '' 'Private utility function for a couple of labels + entry.
              Return istance of entry itself.
          '' '
          Label (frame, padx=10, pady=10, width=width_label,
                 text=text_label) .Pack (side=LEFT)
          entry = Entry (frame, width=width_entry)
          entry.configure (highlightcolor='blue')
          entry.pack (side=LEFT)
         ......
          return entry
