yes, id use anything to prototype game maker is another easy to use tool to do stuff like this as well.
as far as artist im not sure, stuff has changed greatly since back when i started. but just look for a game dev community that you like/fit into and im sure you will make a few freinds who might be able to do the art.
your best option imo is to just design an abstract game that doesnt require good or any art in it and just do it yourself.
