Tkinter: Create an homepage look like

[PeroPuri]

Thank you all! I've made some progress,my frame change but not the one I want: when I click my button the frame that change is the menu one and not the bottom one. How can I solve this? Also I've kinda made a copy and paste so I don't know if the structure of the code became really weird or something. Thank you again.
