People here guided me to GRAMPS, an open-source software project. Yes, I'm new, and Python is my first programming language. My software should not be only a "tree-like" one. There are 254 people in this family tree. I'm trying to find another method. But I think it is better to start with contributing to GRAMPS first. Thanks.
