  class GUI:
      def __init__(self):
          self.root = tkinter.Tk()
          self.root.geometry('500x500')
  
          #Textbox
          first_textbox = Text(self.root, width=25, height=10, bg='yellow')
          second_textbox = Text(self.root, width=25, height=10, bg='blue')
          third_textbox = Text(self.root, width=50, height=20, bg='red')
  
  
          # Packing
          first_textbox.grid(column=1, row=1)  
          second_textbox.grid(column=1, row=2)
          third_textbox.grid(column=2, row=1, rowspan=2)
  
      def start(self):
          self.root.mainloop()
  
  appstart = GUI()
