使用Qt，Wt或NaCl构建框架？

Question

I am contemplating designing a framework to allow for one C++ code base to become a desktop application and a web app for most major platforms (Mac OS, Windows, Linux, and possibly Android). I have decided Qt would be best for desktop builds, however I am conflicted between Google Native Client and Wt for the Web App part.

Wt code may be more easily compatible with the Qt code, however I heard Wt is actually AJAX output so I do not know how much this will impact performance (I plan to develop a game engine with this so I need performance).

On the other hand NaCl, is more, well... native. But it seems to be a mess, especially with the JS integration, I just want to write in C++ and be done with it. Additionally I don't know how compatible it would be with Qt.

I have been researching this for weeks and I do not know much about either. So it really boils down to:

A: Could I literally (or pretty much) replace all the W's in the front of the names of all Wt objects with Q's and have it be Qt compatible code?

B: Is Wt native at all, and how fast does it execute at run time (I cant seem to find an answer to this)?

Answer 1

It would be possible to run Wt as a NaCL application as well, in fact, that would combine the best of both worlds. Wt itself (and its dependencies) build fine with the NaCL toolchain, it's only a connector library that is missing currently. There was an opening for a GSOC project to implement last year, but it didn't happen.
