The most popular until now, but that's because there hasn't been an
alternative. For anyone starting to write a audio/MIDI program today
it's probably a lot easier to use JACK for both audio and MIDI (and with
the -X seq driver option in the SVN version of jackd you can connect
JACK MIDI and ALSA sequencer ports to each other).

Yes. I'd recommend GTK for C and gtkmm for C++. =)

This is a very good idea.

I don't know if there is a hacker's FAQ somewhere, but it would
certainly be useful. It could also have some longer tutorials on how to
write an effect plugin, how to write a synth etc.
