This really wants to be done in (or with the active help of) the X server.
You might want to look at how various accessibility-related programs work.

When A is pressed, grab the keyboard and manage key events yourself (which
is what you want to do anyway, isn't it?) until all the keys you want to
work with are released, at which point you drop the grab.

You should probably look for x.org-related mailing lists.
