No, only the RedPower tubes can go through hollow blocks.

Yes, it is possible to create hollow glass panels. Just slice a glass block in half until you get 8 hollow covers (or whatever thickness you prefer) and arrange them in a hollow-like fashion in a crafting grid (like when making chests and furnaces).
