I could do simple file editing, converting, i have done this before with 
java and c.
Would need to look up on graphic user interface, maybe someone wants
to do that. I would use a text interface for now.

A manual potentiometer would be one solution, i am not sure at all how
one could integrate the "4th axis" of the syringe motor in the G-code.
If one uses a pneumatic system the "potentiometer" would simply be the
pressure regulator.

I'd opt for a leadscrew type, as i want to enable drilling.
I think of a "gantry style" machine.

Yes, i do not think this is possible with a drill cycle at all, is it?
but i would assume one can make a own "paste cycle", like a macro
or what it is called (need to read up on that).
