How do i start creating an actual game?

I have all my story, ideas for puzzles, scenery, characters (+ designs etc) but im just not sure like how to start putting it together to form an actual game. Is there a specific good program i need to use or something? Sorry im very new to this and id just love to get my stories out there through games but im pretty unsure where to go next. Any help will be greatly appreciated!

Edit: Thanks for the advice everyone, im gonna play around with a few things and figure out what works best!
