Is there a good book that shows clearly how to build a simple wooden

2x2 is too skinny, and you want larch from a decent timberyard, not
"construction" whitewood or pressure-treated toxic crap. Bendrey
Brothers if you're around Bristol - my last was costing me £16/cube
foot.

I do like Sobon's books (US-style simple timber framing), but they're
about real "framed" sheds on an 8x8 cube or larger, not a minimal UK
garden hutlet.

Would one of those "sliding" rotary saws be a good tool to cut the
timber? I'm looking for an excuse to buy one

You don't even need the slider for cross-cutting this stuff. If you do
want a slider, make sure that the depth stop allows you to also use it
for cutting halved joints. If you can do that much, they're useful. As
a mere chop saw, personally I can't be bothered as I'll still need
another saw to cut the joints.

Or you can do the lot with a few trestles, G clamps and a decent
handheld circular with adjustable depth. Stanley's nice adjustable
square (heavy aluminium with a swinging bar) makes a good guidebar
for this level of carpentry.

Where could I buy simple fixed windows to fit into said structure?

Recycle. Most of mine are sealed DG units taken from houses or shops
being converted to tiny flats. Can't move for skiploads of things
round my way.
