Normally Tkinter works with a hierarchical system, in which there is one root window to expand other widgets. To solve this issue Tkinte Toplevel. Tkinter Toplevel widgets work as windows which are directly managed by the window manager. Many numbers of Toplevel applications can be used.

Example:
from tkinter import *
appWindow = Tk()
appWindow.title("Window Title-Tutorialsart.com")
appWindow.geometry('350x200')
def window_topLevel():
window1 = Toplevel()
window1.geometry('150x150')
label1 = Label(window1, text="ALL PROGRAMS")
label1.pack()
frame1 = Frame(appWindow)
frame1.pack()
button1 = Button(frame1, text="Click Here", command=window_topLevel, bg="orange")
button1.pack(pady=10)
appWindow.mainloop()
