This has already been done. Check out the source code for HALD. IIRC, it is written in C.

Here is the C source code for a demo program written by me which does pretty much what you want to do. I tested it on a vanilla Centos 5.2 box. It uses DBUS to talk to HAL and Glib's g_main_loop_run to handle events. Enjoy!
