JEWL (John English’s Window Library) is a set of Ada packages for developing GUI-based programs. It has been designed to be usable by complete beginners in an introductory programming course. It does not require a knowledge of any ‘advanced’ Ada concepts before it can be used, and it allows novices to develop GUI-based applications with a minimum of effort. This paper describes the features of JEWL, its design and the philosophy which underlies the design. JEWL is freeware, and can be downloaded from
