I don't think it is easily possible in a cross-platform environment.
But even if your software is one platform only how will you handle
DPI change, theme change and other system changes?

You will have to have some kind of layout system.

See my previous reply.

You are overthinking it.
What if the window will be positioned on half normal DPI screen and
half on HighDPI one?
Or there was a theme change with the start of your software?

As I said you absolutely have to have some kind of layout system or
end up having 100 copies of
same window prepared for a different layouts.

Just accept that there are different layouts available for you that
will handle every possible situation.

You mean positioning controls on the screen with portrait vs
landscape? Or during printing?
Please clarify.

As being said GTK does not use native widgets.
