Cool! What did you use as widget set? Or did you use xlib directly?

For simple playing, you don't need any library. Just write your wav
file directly into /dev/dsp. The usual way to use it is to have a
select() or poll() call in your main event loop and check whether
the file handle can accept more data. If you need it to be fully
asynchrounus, just fork a new process and do the loop there (adds maybe
10-20 lines or so). (dont worry about overhead here. as forking is much
cheaper on unix than on windows, forking to play a wav once in a while is
not going to hurt)
