Well the documentation is minimal, so I suggest you take a look at the
in the wx/examples directory.

After the minimal and hello world examples:
Run wx:demo(). which have exemplifies some more widgets with code displayed.
The demo needs more examples, so if you want to start with something simple
patches are accepted :-)

Larger and probably better code is in observer, as we/I learn wxWidgets the
we use it.

But yes wx is a just a thin wrapper on top of wxWidgets so if you do stuff
that is not
expected or wrong it will crash. I have tried to hinder crashes as much as
I could.

To be safe from crashes somebody will have to write a layer on top wx which
a state of what is happening and what is allowed, a gs on top wx..

PS: Steve I have set you up here :-)
