At a conceptual level, the difference is very simple: A layer is a visible part of an image. A channel is not: it is a grayscale drawable that acts to modify the behavior of some part of the image. As Sven wrote, part of the confusion arises because the top three or four "channels" that you see in the Channels tab in the user interface aren't really channels, in the GIMP sense of the word "channel". There does not really exist a good developer-oriented explanation of the differences between types of drawables, but if you combine the material in the Help docs at http://docs.gimp.org/en/ (particularly sections 2.4, 4.2, and 4.3) with the API docs for gimplayer and gimpdrawable at http://developer.gimp.org/api/2.0/libgimp/index.html it might be enough to be helpful.
