advice on integrating .net application with wordpress

We have a .net application that we’d like to integrate with wordpress. If we want to go the wordpress plugin route, my understanding is that we’d have to rewrite it in php. None of us are php guys here, so we really don’t want to go down that road if we don’t have to. Also, this application has to exist outside of wordpress, so we don’t want to have two codebases to update. Our thinking was that we’d have a page with an iframe in it that would load the application. However, I’m not sure if that’s the best way to go or if any of you have found better ways of integrating a separate app into wordpress pages? Thanks.
