Arduino Project for Anniversary

Hello all! For my lovely girlfriend of soon to be 3 years, I am trying to create something simple but special for her! My idea is a small wooden box, and when you open said box, the LCD screen draws a heart and writes "I Love You!" below the heart or something along those lines. I am very new to Arduino and am not really too sure where to start honestly. If y'all lovely people could give me some pointers (or if you're feeling ambitious and generous, maybe a small guide) on where to start, that would be greatly appreciated! The idea seems fairly simple, but with my extremely limited knowledge, I could be very wrong haha.

(Follow-up question, am I able to implement a program from Python to handle the drawing on the display and such? I already wrote a program that I am satisfied with, just wondering if I can directly implement that or would have to rewrite it for Arduino.)
