Mixing Swing GUI components and JOGL

How does one go about adding JButtons among various other Swing GUI components inside a JOGL canvas? Is it even possible? Is it practical?

If it is not possible/practical/feasible how would you go about programming your own GUI components that work in JOGL?

From stackoverflow

• As an alternative to embedding Swing (or SWT) components within a JOGL canvas, you could use an OpenGL UI toolkit for Java.
