A c++ project has to have a web based interface.
Anyone pls suggest what languages/frontends are the choices here?

Hello,

You might want to consider using PHP as a frontend language for your web interface. It's basically a demented version of C, so you should have no trouble catching on to the syntax.

For something more object oriented, you might want to try Python, as it's getting more and more popular, and although the syntax isn't very similar to C++, it's more strictly-typed than PHP, and so it will help you eliminate errors and bugs.

Hope this helps
