Hey Erich,
I'm currently using a site called Mobincube
webpage to design a similar app. Everything is graphical and it allows for the app to be published both on Apple and Google Play. There is no coding involved, unless you get highly involved. But you can use a database to list your produce, update it, and even set up communications with customers. The great thing as well is that if you design your own app, you can add your own graphics to the app, and really personalize it. You can also put ads on the app and generate some income that way. I use inkscape for the graphics, another free program. Let me know if you need any help getting started.
