I need to query the ID of GUI, in Tkinter, but don't know how to do

Pass the name of the label as an argument to the callback. Below is a

lab = 'test'
menubar.add_command(label=lab, command=lambda l=lab: do_menu(l))
lab = 'quit'
menubar.add_command(label=lab, command=lambda l=lab: do_menu(l))

Another way to do the same thing (a way to "avoid" lambda):
from functools import partial
...
class MyGUI(object):
...
def make_menu(self):
top = Menu(self)
menObj = Menu(top)
for n, lab in enumerate(read_from_database()):
menObj.add_command(label=lab,
command=partial(self.do_menu, n, lab))
def do_menu(self, sequence, label):
# here you know it was the (sequence+1)th entry named label
