Is there a FREE Java GUI designer? [closed]

Is there a FREE (or relatively cheaper) Java GUI designer/builder?

What is replacing Java Swing?

Hint: Oracle has developed JavaFX to replace both Swing and AWT. Since Java SE 7, update 6 it is bundled with Java SE. "JavaFX is a set of graphics and media packages that enables developers to (...) deploy rich client applications that operate consistently across diverse platforms" [1].

Is Java Swing still developed?

Absolutely yes. Legacy swing applications are still supported and enhanced.

Is JavaFX better than Swing?

From a Java developer perspective, both technologies are highly useful in writing pluggable UI components. With its vast UI component library, Swing can provide added advantage to the developer, whereas when it comes to design modern and rich internet application, JavaFX can supersede Swing.

I highly recommend NetBeans's Matisse GUI editor.
