How should I build web app tool to assist in clearing cache faster during development?

Thank you for reading this and thank you even more for helping.

I'm fairly new to web development and I've noticed it's a two or three step process to clear cache. Now I know there might be similar apps in existence, but I thought this would be a good exercise for growth; I just have a few questions. Can this be done with Javascript or should I use Python? Is this a reasonable project for an amateur to take up? Are there any tips or tools of the trade a veteran might pass along to a green belt for creating such an app?

Again thank you for reading.
