Start at the beginning.
There are three parts to controlling an LCD like this:
1) The LCD itself, which will required clocked data presented on it's control lines.
2) The display _controller_, that generates these timings.
3) A processor, that talks to this controller.
The PIC, could probably be used for the latter, though is also probably not a good choice. In general, to do any form of graphics, will require a processor that has significant amounts of RAM - If this dispay supports say 4 bits/colour, you will need 362KB, to hold just a single image for it. Most PICs have at most a few KB. The one you mention, only 768 bytes...
The PIC could not be used as the display controller '2' above. It won't generate the required timings, or have the memory to hold an image.
I have in the past, used a PIC for '3', using it to give intelligence to data from another controller, implementing effectively a X-Y platter type command set, having the PIC to implement algorithms to draw lines, circles, text etc., but the main data wil have to come from another larger processor, and there will need to be a display controller between.
Any 'driver', will be to talk to the display controller, not directly to the display itself. You have not posted what this is.
