Sounds like you are writing a CAD application. Simplest way is to create 4 views, use gluLookAt to change the eye position to be looking down x, y, z axes (positive or negative). For isometric not sure of the exact angles but I believe a 45 degree rotation about the y axis and 30 up rotation about the x axis will probably work for your eye position.

on http://nehe.gamedev.net
is a new Tutorial, which Describes Multiple Viewports

If you're using MFC, I guess you can use the CSplitterWnd class.

Or maybe you can just create one big view, and split the OpenGL viewport up,
so it looks like multiple views.

The source distribution of GLFW (http://hem.passagen.se/opengl/glfw) has a simple demonstration of just that (four views, using four viewports/scissor areas in the same GL context/window).
