If you are writing for a specific hardware, then you might want to just provide
a driver for it, here is a sample touchscreen input module for you:
    http://cgit.freedesktop.org/xorg/driver/xf86-input-elographics/tree/src/xf86Elo.c

If you are installing wayland or something other than X, then there's probably
a different method.
