● wxWidgets:● wxGlade
● Qt:● Qt Designer● Qt Quick/QML

The New JavaFX
● JavaFX 2:● Java API for Java SE.● Eventually a replacement for Swing.
● SceneBuilder● FXML

Having Good Architectures
● Separate concerns.● MVC (model, view
controller), MVP (model view presenter).
● Mediator.● Façade.
● Code for structure and logic.
● CSS (cascading style sheets) for presentation.
