The basic dimensions are easy and really the only tools you need are mitre saw, Pocket Hole Jig, a drill and a sander.

I cut 45 degree mitres on the ends of the 12 inch boards.
Seven of the frames parts were assembled in the shop using wood screws and the last section was screwed together when placed around the tree.
|completed frame, 26 1/2 inches across|
When I put the frame together I used Pocket Holes, this is how I clamped the frame together when I screwed it together.
After I screwed the frame together I cut the over hang off with a hand saw and then sanded things smoothish.
When the project is finally done you get this:
