DIY glass block basement windows?

[Phil Morgan]

Question for all you handy folks out there. I have a brick duplex and am currently closing on my second one and they are both in need of glass block windows in the basement.  Is this a DIY project or something that should be let to the pros?  I am pretty handy, have done total gut down to the studs bathroom and kitchen rehab projects, but never handled glass block.  I see the preformed 6 or 9 block windows at HomeDepot that would fit perfect and already have the dryer vents in them but am clueless on how they are installed.  Thoughts?
