fix an example of wxwindows listed on rentacoder.com

[Eric_Dexter at msn.com]

     The code in question is at https://sourceforge.net/projects/dex-tracker
I am trying to get rid of the part of the example where you have to
use run.py.  since I am stuck and it is driving me nuts I have put it
up for bid at http://www.rentacoder.com/RentACoder/misc/BidRequests/ShowBidRequest.asp?lngBidRequestId=676174
If I can get this to work well I have another small c project that
will allow me to compete with sep (stienburg) :)
