Unfortunately, there is no easy way to integrate the designs of one system into another. The best you can do usually, is to copy and paste the HTML output from the WordPress powered site, into the header/footer of the other system. However that doesn’t allow for menus, sidebars etc. to be dynamic.
The ultimate goal
To get around the performance issues of loading two softwares at the same time, we have developed a WordPress plugin which caches the output of your WordPress theme and stores it in static files on your server. By including those files in the other software, you can totally restyle it via the WordPress theme and those changes are automatically updated every 60 mins (or however long you choose).
We use the PixoPoint Theme Integrator in our support forum.
