xkb keyboard descriptions map scancodes (from the kernel) to a number of
literal symbols. This is (on most boxes) responsible for different keyboard
layouts, so basically you can map anything you want.
xkbcomp -xkb :0 mylayout.xkb
will dump you current description into mylayout.xkb. You can then play with it
and load it back into the server with xkbcomp mylayout.xkb :0.
(There's a few caveats I'll skip for now).

Integrate with xkeyboard-config's RMLVO descriptions. There's a simple
description (skipping all the nasties) on
As for the button->keyboard events, that's a bit harder as they are treated
very different by the server and can't be mapped as easily.
