Your problem is that in your CharLoop method, the WriteText triggers a
EVT_TEXT, which in turn triggers the method again, causing an infinite loop.
This is a problem - infinite loops are bad! You also want to get the text
from the event, not from the control itself. Use

I think what you want is to just leave it as a regular TextCtrl. Try
removing the parts of your code that deal with an EVT_TEXT, for right now.

I don't exactly understand what it is you want as the end result, but a
regular TextCtrl without the EVT_TEXT event bound should solve your problem.
If you only want it to show one character at a time, then you're better off
not using a multiline TextCtrl. However, if you are trying to get this to
work as a small example, then I would suggest that you move on to dealing
with multiple characters instead of restricting yourself to a single one.
Other widgets are better for getting single characters as input.
