wxWindows vs. MFC

EvanED queries: I'm going to devoloping a chess program, and was until a couple days ago planning to do it in MFC. But then I ran across wxWindows. I think it would be cool if it were able to run under Linux. (At the moment, I do not have Linux on any computer but will as soon as I get my own machine.) Do the benefits of supposed cross-platformness outweigh the drawbacks of having to learn a new system and not having all the (incredibly wonderful) automatic code generation features Visual C++ provides for MFC programs? Or would it perhaps be better to write it in MFC since I am reasonably familiar with it then port it to wxWindows?"

But development on wxWindows can die off...

... leaving you effectively in the same situation as having your vendor die off or stop supporting the product. The only difference is you could continue development on your own. But how many people are really going to do that?

If you want real portablity, use an ASCII terminal for the display. You'd have a better chance of getting that to work 10-20 years from now than wxWindows, Tk, or MFC.
