Thanks, sounds cool. You plan to write an interface the way totem and others
are interfaces around libxine and gstreamer? If so I must dissappoint you,
because libvlc doen not yet have a suitable api for that. We know it's a
pity, and it might change in the future, but right now we have more than
enough to do developing the internal stuff.

qvlc is not built because the interface was never completed, it does not do
much except print "not implemented" on stdout when you press buttons.

The right task for you would probably be trying to complete the qt
interface. But it sounds as a terrible waste, as you will do everything the
wx interface do over again. If you have kde installed you could start with
kde interface since it got quite a bit further than qt interface before
interrest dropped. Though the obviously simplest solution would be to
install wxwidgets. It's not _that_ big is it? If you compile from source you
could build a wxwidgets that only depend on X, not gtk (at least so I think).

vlc-config is mainly meant to be used during building of vlc, but this
changed recently. If you have up to date svn version of vlc you can use
"vlc-config --cxxflags --libs external" to get flags for compilation in an
external project.

Hope this helps.
