D-Bus

Hello QtCentre users,
I recently bought an ASUS eeePC. So far I haven't been able to find any Qt/KDE application to manage the devices on this laptop (card-reader, camera, bluetooth, wi-fi etc). Those devices can be turned on and off by modifying some files in the /sys filesystem.
I would like to write an app to manage the devices on my eeePC. I was thinking I should write a daemon that toggles the devices (it needs to be run as root) and GUI. The question I am asking is: is D-Bus suitable for this project? If it is, where can I find a tutorial to get me started? (I looked over the qt docs but the information is pretty scarce)
