what you need has to deal with gc's (graphics context)

(see the gdk reference manual)

1. Create a GdkGC (say mygc)
2. Create and allocate a GdkColor
3. Assign it to the foreground

and use it like
gdk_draw_line(widget->window, mygc, x1, y1, x2, y2);

NB: if it doesnt help you, tell me, I had code example, but not right now ;-)
