gl2 is the 2d graphics language used for drawing on isidraw and isigraph
controls. It has stayed mostly unchanged as J has moved from Windows to
GTK to Qt.
It operates at the level of set color, set pen, draw line, draw
rectangle, set font, size text, draw text, etc.

In J, gl2 and opengl is unrelated.
Modern OpenGL has a steep learning curve, there are many tutorial
resources
on internet. Perhaps read text books like OpenGL superbible.

FYI, as there are no longer any openGL labs, this line at
http://www.jsoftware.com/jwiki/Guides/Window%20Driver/gl2%20Command%20Reference
is misleading:
Lab "Graphics - gl2 commands" gives an overview of the isigraph control
and gl2 commands. See the other graphics labs for information on other
aspects of gl2.
I suppose that currently the best way to learn GUI/openGL programming is
to go through the qt demo code and
the wiki reference guides?
