Would it be rude to answer "use the source"...?

GTK+ uses the low-level GDI API to draw its widgets and text. Functions
like LineTo(), Rectangle(), Pie(), ExtTextOutW().

Text is drawn (in Pango) using the ExtTextOutW() function, and usually
(I think) first to a bitmap, and that bitmap is then blitted onto
the screen.

I think "edit controls" is the name used for the Microsoft-supplied
"widgets". GTK obviously doesn't use those, as it is a widget set
itself.

About your problem, how to make GTK work with screen readers on
Windows, I am sorry, I don't know. I will have to read up on how they
work, and what should be done and where, in order for them to work
with GTK. There were a couple of messages on this subject earlier this
month on gtk-devel-list, with the subject "windows gaim screen
reader". Especially, check the message from Bill Haneman.
