I use an Azerty keyboard. How can I handle keybindings easily?

As a Belgian, I use a non-qwerty keyboard with AZERTY (A/Q switched, W/Z switched, M/; switched, changed layout of symbols near alt gr). This is rather annoying, especially on games like Oblivion, Fallout or Morrowind (forces QWERTY), The Wolf Among Us (uses the letters instead of the keys for keybinding, which gets VERY annoying since it's quicktime heavy) and games which don't allow to rebind keys (which is surprisingly many of them these days).

I have a dual monitor setup, which means I often am passively listening to Youtube or something while playing some games. I'm looking for a solution for games which don't allow key rebinding and use the letters, but which does not involve setting my entire computer to qwerty and where I can set it for individual games (because the games with rebindable keys don't have this issue).
