How to Integrate Goal Meter and Messages on Website

We, a non-profit organization, have someone important in our community who is very ill, and we are looking to set up a page called Acts of Kindness, where people can go in and write a short message on what their act of kindness was (inspired by this person we are honouring). These messages could show name OR be anon. There would be a goal meter that allows us to see progress to our goal of 1800 acts of kindness. This is simply message based (not donation based). Therefore the goal progress meter would need to count submissions instead of money. Platforms?
