I have to explain this would be my first every circuit project, I have a 23 pin connector and I have an old gfx card, I could take the vga connector off. so all that I guess is going to be needed is the small circuit board, so any advice on how I would go about creating this?
You don't really need to make a PCB, just solder the wires directly to the connectors.
Two of the pins get two signals from the 23-pin connector (and can be soldered directly to the connector inside the A1200) and the remaining 8 are Reg, Green, Blue, Hsync, Vsync and a couple of grounds for the 15-pin VGA connector.
The circuit board does absolutely nothing else than look good (and make the product user friendly).

EDIT: Pinouts:
Top side, connector to the right (like in this pic
http://amiga.resource.cx/photos/scanmagicint.jpg)
Top pin: Green, VGA pin#2
2nd pin: Hsync, VGA pin#13
3rd pin: GND
4th pin: Vsync, VGA pin#14
Bottom pin: Red, VGA pin#1
Bottom side, connector to the left
Top pin: Alice pin#77 (? 7th pin from the top, l/h side, same side as pin 1)
2nd pin: Blue, VGA pin#3
3rd pin: Alice pin#79 (? 5th pin from the top, l/h side, same side as pin 1)
4th pin: GND
Bottom pin: N/C
I have the version with the Alice clip-on adapter thingy myself, so I don't know the corresponding pins on the 23-pin connector)
