There is an official GUI for John the Ripper: Johnny. Despite the fact that Johnny is oriented onto JtR core, all basic functionality is supposed to work in all versions, including jumbo. Johnny is a separate program, therefore you need to have John the Ripper installed in order to use it. More information about Johnny and its releases is on.
