I can't think of a way to do this. I'd like to have a bg image and be
able to scroll text over it without obscuring the bg except for the
characters themselves.
It would also be great if one could use a custom font. When I searched
for this, I found that I'm not alone in wanting to do this but there is
no cross-platform way (one has to use either twapi for windows or put a
font file into ~/.fonts or something like that for unix).

What I would want is a text widget with a transparent bg so I could
"place" it on top of an image (label widget). The scrollbar would not be
transparent, but I can live with that.
I didn't think it would work, but I tried text .t config -bg {} and sure
enough, I got an error.

I really doubt you'll find a cross-platform way to do this--unless you feel androwish / undroidwish is a viable option.
Since it renders in SDL, using FreeType, you can embed fonts and it will work across all supported androwish platforms.

So you just need one image item and one text item. Of course, scrolling will need manual update of coordinates, and possibly logical clipping for performance.

Yes, sorry for not stating it clearly :)
