I have made numerous beutiful tanks. I use plexi-glass though. To put the peices together, you use something called "weld-on". It is sort of hard to find, but if you look around, you will probably find it. The weld-on will litterally fuse the plexi glass together. After you do that, I ussually put in some Aquarium selant, just becuase. The only problem with plexi is its tendancy to scratch, I am always finding myself telling people not to touch, or get anything near it, ha ha. But besides that plexi-glass tanks make for a very cheap, easy to make custum tank. I have never made a glass tank. Good luck!
