Microsoft Access is probably the best fit for you.
However, beware the danger of ending up with your business fundamentally built on Access. Many products make it easy to program, there is no product that makes programming easy. Just underneath the candy shell, the horrifying Turing chaos waits for you the same as any "real" programming environment, and many is the person who has inadvertently released an Elder God from his tasty confectionery prison to consume their business whole.
I'm being a bit flowery, but I am serious. It's happened many times and I've seen it myself once. Use the tool responsibly; the poky bits haven't been taken out, just moved around a bit.
