That's not a JFileChooser type dialog. It is a regular dialog with some labels, icons, buttons and a hyperlink. Only if you press Save will a file chooser be shown.
You could do the same yourself, by making a custom JDialog subclass. Save will call the JFileChooser, Cancel will close the dialog and Open will open the file. (That is a bit harder than the rest though). You'll have to play around a bit with the layout as well.
As for the hyperlink, if you really need one there are
some examples on Java2S.
