Epoxy is the preferred choice for that purpose, You can lay the strips up dry and then roll epoxy over them.

Pipe clamps are a bit much for this purpose. If you are making 1/4" or less by 6" or more panels, you will get a lot of buckling.

I usually make paddle blades this way and I staple the edge pieces to my bench.

Glass on one side will warp something terrible if the humidity changes.

If you bend panels green, you will have appearance problems and perhaps some structural problems.

If you build panels with an amount of wood and glass that matches the stiffness of the plywood and let it cure you should have no problems in bending it.

In any case use a nonblushing epoxy.
