I know this is an old post, but Glamour Glow, as a filter, is a part of the Nik Efex Color Efex Pro plug-in. Chris' answer was right though. You can do it manually. Guassian Blur and Screen are the manual methods for creating a glow. There are Surface Blur techniques as well. Sometimes, other Blending Modes work better too, depending on what your blend/base layer pixel relationship is.
