CRUD (create, read, update and delete) is what you need. Google “wxpython crud” and you will find videos, code, and tutorials that will help you with creating python code to allow simple CRUD operations such as what you are trying to do. Unless there is some other reason you need to avoid using the tools that are designed to your best bet is to use those tools.
