[Haskell-cafe] Study GUI and FRP sequentially or concurrently? Superimposing graphics and text.

I personally picked up both wxHaskell and reactive-banana at the same time
and it was fine. In practice the two are almost orthogonal—reactive-banana
completely supplants parts of wx and doesn't touch the rest at all, for the
most part. (I recall some wx-specific quirks that leak out into
reactive-banana code, but nothing too bad.)
For me, the examples included with reactive-banana-wx were probably the
most useful learning aide. Once you figure out how the examples work, you
can modify them and see the changes right away, which is enough of a
stepping stone to figure the rest out from the API docs.
As far as superimposing text on an image, that should only take
wxHaskell-specific code. You'll probably have to mess around with the
layout, but the two widgets (text and image) should still be the same and
so act the same from the perspective of reactive-banana.
