I would like to create a Basic card game ? where to start ?

i have a fully working prototype, all done in c# wpf with textboxes only, all the logic and the gameplay loop is done and working, i just need some sort of 2d art to make it beautifull : )

its a very simple card game who use the standard 52 cards deck as gameplay assets
i need some tutorial on how to draw a game, do some colorised squares who moves and change colors, apply animations, handle interactions etc
i have never touched a game engine before ...
