[Tkinter] How to add multiple frames to main window

[Dandy_Don]

I am stumped. I can't figure out how to add multiple frames to the main window in a GUI....

I have a system that uses multiple winches to raise/lower things. I want to create a GUI that shows each winch & allows for control of them.

Since the winch frame is the same for each winch (except for the winch name, "Top Right", etc.) I created a class for the winch frame. Then I created a main app class. I can't seem to get the winches added to the main app, though....

from tkinter import  *

class WinchFrame(Frame):
    def __init__(self):
        super().__init__()

        #  CREATE WIDGETS:
        self.winch_lbl = Label(text="Top Right", width=15)
        self.lbl_btn_up = Label(text="UP")
        self.btn_up = Button(text="OFF", width=12, fg='green')
        self.txt = Text(height=1, width=50, bg="light blue")
        self.lbl_btn_down = Label(text="DOWN")
        self.btn_down = Button(text="OFF", width=12, fg='green')
        #  LAYOUT:
        self.winch_lbl.grid(row = 1, column = 0, padx=5, pady=5)
        self.lbl_btn_up.grid(row=1, column=1, padx=5, pady=5)
        self.btn_up.grid(row=1, column=2, padx=5, pady=5)
        self.lbl_btn_down.grid(row=3, column=1, padx=5, pady=5)
        self.btn_down.grid(row=3, column=2, padx=5, pady=5)
        self.txt.grid(row = 5, column=1, columnspan=2, padx=5, pady=5)


class WinchApp(Tk):
    def __init__(self):

        self.frames = {}
        self.frames["Top Right"] = WinchFrame(parent=container, controller=self)
        self.frames["Top Right"].grid(row=0, column=0, sticky="nsew")

        self.Top_Right = WinchFrame()
        self.Bot_Right = WinchFrame()
        self.Top_Right.grid(row=0, column=0, sticky='nsew')
        self.Bot_Right.grid(row=5, column=0, sticky='nsew')


if __name__ == "__main__":
    app = WinchApp()
    app.mainloop

Any help you can offer will be greatly appreciated!
