[Python] Creating a dynamic window with Tkinter [closed]

I am trying to create a simple CRM using Tkinter but I have a problem with creating dynamic buttons and title.

I want the title and buttons to readjust their size depending on the window size. I tried to make a grid_rowconfigure for each button but it didn't solve it.

This is my original code for the main page:

def __init__(self, parent, controller):
tk.Frame.__init__(self, parent)
self.controller = controller

# Configure grid layout for the main page
self.grid_columnconfigure(0, weight=1)
self.grid_columnconfigure(1, weight=1)
self.grid_columnconfigure(2, weight=1)
self.grid_rowconfigure(0, weight=1)
self.grid_rowconfigure(1, weight=5)

# Centered title
label = tk.Label(self, text="CRM Dashboard", font=("Helvetica", 24))
label.grid(row=0, column=0, columnspan=3, pady=10, sticky="n")

# Create three frames for the columns
customer_frame = tk.Frame(self)
customer_frame.grid(row=1, column=0, padx=20, pady=20, sticky="nsew")
customer_frame.grid_rowconfigure(0, weight=1)
customer_frame.grid_columnconfigure(0, weight=1)

transactions_frame = tk.Frame(self)
transactions_frame.grid(row=1, column=1, padx=20, pady=20, sticky="nsew")
transactions_frame.grid_rowconfigure(0, weight=1)
transactions_frame.grid_columnconfigure(0, weight=1)

sales_frame = tk.Frame(self)
sales_frame.grid(row=1, column=2, padx=20, pady=20, sticky="nsew")
sales_frame.grid_rowconfigure(0, weight=1)
sales_frame.grid_columnconfigure(0, weight=1)

# Buttons under Customer column
customer_label = tk.Label(customer_frame, text="Customers", font=("Helvetica", 16))
customer_label.pack(pady=10)

add_customer_btn = ttk.Button(customer_frame, text="Add Customer", command=lambda: controller.show_frame('CustomerPage'))
add_customer_btn.pack(fill='x', padx=10, pady=5)

delete_customer_btn = ttk.Button(customer_frame, text="Delete Customer")
delete_customer_btn.pack(fill='x', padx=10, pady=5)

search_customer_btn = ttk.Button(customer_frame, text="Search Customer")
search_customer_btn.pack(fill='x', padx=10, pady=5)

# Buttons under Transactions column
transactions_label = tk.Label(transactions_frame, text="Transactions", font=("Helvetica", 16))
transactions_label.pack(pady=10)

add_transaction_btn = ttk.Button(transactions_frame, text="Add Debt", command=lambda: controller.show_frame('TransactionsPage'))
add_transaction_btn.pack(fill='x', padx=10, pady=5)

remove_debt_btn = ttk.Button(transactions_frame, text="Remove Debt")
remove_debt_btn.pack(fill='x', padx=10, pady=5)

search_debt_btn = ttk.Button(transactions_frame, text="Search Debt")
search_debt_btn.pack(fill='x', padx=10, pady=5)

# Buttons under Sales column
sales_label = tk.Label(sales_frame, text="Sales", font=("Helvetica", 16))
sales_label.pack(pady=10)

sales_btn_1 = ttk.Button(sales_frame, text="Add Sales Record", command=lambda: controller.show_frame('SalesPage'))
sales_btn_1.pack(fill='x', padx=10, pady=5)

sales_btn_2 = ttk.Button(sales_frame, text="Delete Sales Record")
sales_btn_2.pack(fill='x', padx=10, pady=5)

sales_btn_3 = ttk.Button(sales_frame, text="View Sales Summary")
sales_btn_3.pack(fill='x', padx=10, pady=5)
