Hi Group, help please!

I want to build a glass-walled cube. One side removable/hinged.
I will be using plate glass (6mm approx)
The cube is to be 2 ft. square.
So components are six pieces of plate glass each one 2ft x 2ft.
Now, the problem is how to 'stick' the joints.
I would prefer not to use any bracket supports on the joints - just 'glue'.
Can it be done?
What type of joint to make? (DIY of course - no melting of glass!!)
