FLib is a free, open source library of high-quality Java components. It currently contains wizard and calendar components. The wizard component makes it easy to create multi-step user dialogs. The calendar component can be used by itself or as part of a combo-box drop-down.

While the components are in English, complete localization is possible. The calendar component is mostly internationalized as is and automatically adapts to the locale.
