How to place widgets on top of background image on tkinter window

in this section we will be placing widgets on top of a background image in tkinter image. please refer previous_post to understand basic of setting a background image

below is the code for the screen above.

 # program

 try:
     from Tkinter import *  # supports Python 2
 except:
     from tkinter import *  # supports Python 3
 
 mw = Tk()
 mw.title("AETies : Automation Expert Technologies")
 mw.geometry('400x50+50+50')

 pic = PhotoImage(file="./bg_2.png")
 lbl = Label(mw, image=pic)
 lbl.pack(fill=BOTH, expand=YES)

 btn = Button(lbl, text="click on below image button to close", highlightcolor='red', command=mw.destroy, padx=5)
 btn.pack()
 pic_1=PhotoImage(file="./favicon.ico")
 btn = Button(lbl, image=pic_1, highlightcolor='red',padx=5, command=mw.destroy)
 btn.pack()

 mw.mainloop()

as mentioned in previous post, if we skip step 3, background image will not be visible.

 # program

 try:
     from Tkinter import *  # supports Python 2
 except:
     from tkinter import *  # supports Python 3

 mw = Tk()
 mw.title("AETies : Automation Expert Technologies")
 mw.geometry('400x50+50+50')

 pic = PhotoImage(file="./bg_2.png")
 lbl = Label(mw, image=pic)
 lbl.pack()    #bypassing this, refer above code to know what we are bypassing

 btn = Button(lbl, text="click on below image button to close", highlightcolor='red', command=mw.destroy, padx=5)
 btn.pack()
 pic_1=PhotoImage(file="./favicon.ico")
 btn = Button(lbl, image=pic_1, highlightcolor='red',padx=5, command=mw.destroy)
 btn.pack()

 mw.mainloop()
