International Resources
A great European resource for painted stained glass is The British Society of Master Glass Painters. They have a world wide membership but focus more on British painters. There site has some good links for images of windows and info about stained glass painting in general. In France, near the cathedral at Chartre is the Centre International du Vitrail. They have classes and a library on site as well as a gallery. Having been there, it has the look of an art society in the US. In New York there is the New York Carver, which is connected to the stone carvers at Saint John the Divine. This site and the church is a great resource for details about life in the Middle Ages. If you go to New York, you must stop by the Cloisters as well. It is the largest museum of objects from the Middle Ages in New York and is part of the Metropolitan Museum of Art.
Also, here is a essay written by Dick Millard about the process of designing a window for a church client.
In it he writes,
"The first step in my process of creating a design is best described with a phrase I coined years ago: Design Catalysts. By my definition, a design catalyst is any element which is capable of providing and defining parameters within which one commences design. Such catalysts can range from a subject (religious or otherwise) to a color field, an emotion, an aerial view and indeed all the way to the client's budget. In essence any idea from any source can be a design catalyst."
