Reflections that large and intense are never going to look good with cubemaps. The best solution is setting up real-time reflection, then plugging the resulting rendertexture into the cubemap's distortion code in so that it wraps across the surface correctly.
That's a lot of work, needless to say. I'd probably choose instead to make a high-res custom cubemap with indistinct, generic reflections that can be applied anywhere without looking too dodgy. That or give up on the idea of reflections at all! (One final possibility: convert the windows to models and apply high-exponent phong.)
