There's going to be a teach mode and a learn mode. I considered making
them separate apps, but this seems more manageable before someone cares
about hacking on the code.
So far I'm mostly just setting up the screen for teach mode.
I'm assuming the edit boxes for each word need not support more than one
line. Also not bothering to handle line-wrapping.
I should make 'new word' a real button. But it's possible I'll never
need another.
