In recent years, not only functionality but also usability have come to be required in software. In order to develop a highly usable GUI (Graphical User Interface) application, it is effective that end users evaluate their GUI and the results of the evaluation are reflected on the original GUI. In these cases, it is necessary to replace a widget with another widget, and to reconnect the new GUI part with the original body part. When widgets are replaced, the operations are usually changed, but the roles of the GUI are seldom changed. In this research, we propose a development method for GUI applications with easy operations and also a method of automatic reconnection between GUI parts and new body parts. This reconnection is realized by classifying widgets according to their roles and by replacing methods of widgets with abstract methods categorized by common roles.
