Code :

Libraries Required: cmd => pip install customtkinter

import sqlite3

from tkinter import *

from tkinter import messagebox

import customtkinter as ctk

# Database setup

conn = sqlite3.connect('blog.db')

cursor = conn.cursor()

cursor.execute('''

CREATE TABLE IF NOT EXISTS posts (

    id INTEGER PRIMARY KEY AUTOINCREMENT,

    title TEXT NOT NULL,

    content TEXT NOT NULL,

    created_at TIMESTAMP DEFAULT CURRENT_TIMESTAMP

);

''')

conn.commit()

# Functions

def create_post():

    title = title_entry.get()

    content = content_entry.get("1.0", "end-1c")

    

    if title and content:

        cursor.execute("INSERT INTO posts (title, content) VALUES (?, ?)", (title, content))

        conn.commit()

        messagebox.showinfo("Success", "Post created successfully!")

        title_entry.delete(0, "end")

        content_entry.delete("1.0", "end")

        display_posts()

    else:

        messagebox.showwarning("Input Error", "Please provide both title and content!")

def display_posts():

    cursor.execute("SELECT * FROM posts ORDER BY created_at DESC")

    posts = cursor.fetchall()

    

    posts_listbox.delete(0, "end")

    for post in posts:

        posts_listbox.insert("end", f"{post[1]} - {post[3]}")

# GUI setup using CustomTkinter for modern design
