I need to make a non-standard sized internal door (just a frame with
two large glass panels).
I can go to my local B&Q/Homebase and buy the right cross-section
softwood, but as it dries out it may warp.
Thus, should I go for a hardwood - or treated softwood - or what?
I don;t think the likelihood of warping is related directly to whether
it's hardwood or softwood, it's more related to how well seasoned it
is. I would think that your answer lies in finding a good timber
merchant who will be able to sell you material that won't warp, or at
least will warp only to an acceptable degree.
I suspect also that much of the skill in designing and making a door
lies in making it so that any warping will not affect the door too
You could by a standard door and cut it down. That is what some joiners
shops would do. All the rebates are cut and all you have to do is make
sure the section is joined together OK. Simple lap joints will do.
Why are you putting glass in it, the door will weigh a ton as you need
reinforced glass. Will it need to be fire proof?
What used to let doors down some time ago was the technique of using
dowels instead of motice joints. I don't know if the method is still in
use these days. There was almost no strain support in the design. As for
treating the wood, most of these B&Q type places have overdry timber. If
your house is not som dehumidified as those places you will get some
expansion. Look out for clean knot free timber that is straight grained
and store it (under a bed?) out of the way somewhere flat until it takes
on the moisture it will be used in, or just get on with it and be
to fettle it a little afterwards.

Those with large inset panels, or an overskin of mdf are generally Ok
- those big panels make for a self-supporting frame.
I make a lot of simple rough stable doors - just a 4' square of 18mm
ply with an inner square frame of 1.5"x3.5" tanalised softwood nailed
onto it - no diagonals. They never drop until the wood rots out. The
ply takes care of the stress and strain, and the softwood gives it
some rigidity and also gives enough bulk to put the fittings on.
