I think everything is good ,but when I compile , cb shows error:
------------- Build: default in access ---------------
Linking executable: wxwidgets_u.exe
D:\cplus\MinGW\lib/libmingw32.a(main.o):main.c:(.text+0x106): undefined reference to `WinMain@16'
collect2: ld returned 1 exit status
Process terminated with status 1 (0 minutes, 0 seconds)
0 errors, 0 warnings

I have no main.c, why the compiler want it?  Please help me, thanks.

Correct a mistake: <Option output="wxwidgets_u.exe" /> at 10 line of project file

Here is the problem

<Add option="-DWXUSINGDLL" />

You aren't using a dll build remove the above option from compiler #define's and you should be set.
