just in case i'm not able to find a glass shop(that sells glass tubing) near my location and have to change my entire plannings--

how would i be able to build myself a tank? what materials would be needed? i'm sure i can locate a window shop and ask for a **x** sized glass window for the tank. just need to know out of what i need to build the tank of(wood/iron/etc) and why that specific kind of material.
