Both tkinter and sqlite3 are very well documented. You can also find many examples and tutorials online. If you don't know any of them, it would be better to first start with tkinter, and design the application. After you're done you can start implementing sqlite3, which would only take few hours if not less. We can't write the code for you, but if you make an attempt, we may be able to fix your code. Good luck!
