Begin to code an easy desktop Timer app — advices

Hey guys !

I would like to create myself a timer “software” which would also serve as some sort of tracker for my activities. I know a lot already exists but actually building my own also seems to be some good practicing.

Could someone give me a hint about where to start to at least build a little timer ?

I am learning some Python and have learned some SQL up until now, so I intend later to add a database with different activities and eventually some graphs and stats, sort of like the Anki app.

I’m sorry if my question is a little vague : now that I know a little code, it’s the more fundamental knowledge about how to build a little program which I lack.

Hope you could help me with that,
and thank you for your attention anyway -

I hope to hear from you !
