just make the clock example on
MMhell's Tutorial "Writing your first add-on"
google "first add-on"

If you have any programming experience you should be able to pick it up after that using
wow wiki

btw all the stuff your trying to do can be done with Discord Art and Discord Frame Modifier

cept the minimap thats always gonna be a circle afaik maybe you could cut the sides off( and some info) to make it look like another shape bu underneath it will still be a circle
