dumb question #2...

i'm working on a program for my calculus teacher about steiner points. you input the vertices, it draws the triangle and finds the steiner point. i have no trouble finding the point or anything, but i don't know how to get a graphics oriented program (using GUIclass) to receive values from a console based program. can anyone help me?

by the way, the terms i used for that explanation might be off.. i taught myself c++, and probably missed some terminology somewhere along the line.

thanks in advance.
