What do you mean? Calling glClear affects other windows stuff? Usually all buttons/labels/edits are always repainted with WM_PAINT message. Its not OpenGL task to repaint them.

As I think you try to win performance, trying to disable GUI elements redrawing within a window. I dont think you'll receive serious results, but you may handle WM_PAINT message by your own and allow window to repaint only if you need it (simply avoid calls to defWindowProc when you received WM_PAINT, and call it not every time...). Hope, this helps.
