Need Good Program for Small Buildings/Sheds

Can anybody help me "SOS" ; I am trying to find a simple hobby shed design software program. What I am finding is complicated AutoCAD & the likes. I need a program that asks me the dimensions of the floor, walls, roof, placement of doors, windows exterior finish etc. I am a computer dummy, and just need a program with wizards, like my old Printhouse program that would allow me to design a little shed/shop for the back garden, somewhere I can hide..
