Groundhog needs contributors, and not only programmers. Some GUI expert can have some fun reviewing and making constructive suggestions.Throught I (Juanjo) am an experienced programmer on other languages, my own Java skills are probably not elite since Groundhog was my first (serious) Java project, so expert Java and Android programmers could help. If you want to help, take a look at the roadmap (I'll implement all of it eventually, but you could speed it up!): https://launchpad.net/groundhog/+announcement/5352
