Trying to make a CNC pcb router

[vertigo]

I guys, I have for about 3 months been trying to develop a cnc pcb router. I'm finding it very hard to get information about designing software to run a g code that is exported from Proteus. At the moment I have the g code in a spreadsheet in excel and I'm using VB6 to design the software to run the program gui. To start with, well until I get the project working I'm using two Parallax Servo motors to control x and y axis. Does any here have experience with programming software to do this? or has someone done one of these projects themselves and can help me develop my own.

Here is a part of the g code.
