WxWidgets was the default, plain, graphical, interface to VLC, made using the WxWidgets library (Linux users may need to have this installed). It was used as the default interface on the Windows and Linux versions of VLC and have been replaced by the Qt Interface since 0.9.0.
It is known as the "wx" interface, so you can (or was able to) force this by running
vlc -I wx
If WxWidgets is not available, it will probably revert to using the rc (console) interface, even if you force it. The most likely reason for this is if WxWidgets hasn't been installed, or if it wasn't linked in (using the ./configure). See compiling VLC  for information on compiling.
