Make a login window without exit options [closed]

  java, python, user-interface, window, windows

So, I want to make a window with a login window in the PC application that cannot be closed without entering the correct ID Password.
You can say like in electronic stores you see laptops running a specific video or program which cannot be exited or switched to another window or does nothing other than just displaying what the program set.
so like that, I want to make such a window that stays there till I enter the ID password correctly then I can access my PC.
