Need to make a shelf or table for the top of my TV

I need to be able to put plants on top of my TV and need a shelf/table of some sort to put them on.  The tv is on a 15" deep microwave cart and there is about 2" clearance on either side.  The cart is 25" wide.  I have 15" wide 3/4" fiberboard that I can cut to needed width but can't come up with a good way to make it stand up (independently of the tv).  I thought about just putting some legs on the board but am concerned that this will be strong enough to hold the weight of a plant (let's assume 35 lbs but I doubt I would put anything that heavy on it).  Here is photo of what the table/stand will go on and the red lines are what I hope it to look like.  Any help would be appreciated.  Oh, and it has to be CHEAP!  I've already spent $15 on 8' of board and don't want to spend a great deal more.

Oh, and for the record, I am NOT skilled in carpentry, nor do I have time to learn. I need this REALLY simple. I can cut and drill and insert screws (and even glue) but please nothing complicated. Thank you.
