Is there anyway you can make your plugin generic?

Im looking for a plugin that would allow registered users or customers (current or past) to be able to upload a picture and text to a page, that is fashioned like a “memorial wall”… pic with some text, then another one next to it… etc. dropping down to another row, etc. Can your plugin be modified to do this? I wa hoping it could stand on its own and not be tied to the check out page or based off a product… thx
