i don't have those sensor, but sure i'm willing to help if you provide me some link to.

It's not a bug, it's a random feature.
There's no problem, only learning opportunities.

It doesn't use any specific sensor, rather the comparators inside the PIC.. If there are many capacitive areas, they multiplex the comparator. Check this link out:

It tells all you want to know (and more) about the concept.
I've done 4 wire resistive touch controllers with a PIC, but this is much cheaper to implement. Just copper squares on the backside of a circuit board, with your PIC and such, on the top...

Seems pretty straight forward to me.
which pic do you plan to use?

Right now I'm thinking the PIC16F690 since it has two comparators and I have a Microchip demo board that's looking for a home... I've also used it's little brothers: 16F677's and 16F687's on other stuff..
Cheers,
