Thread: Two GUIs in one, possible??

Hi I don't know if this is the right place to leave this message.
Btw I created a GUI using DirectX 9 and I'd like to know if there's a way to create an area to include another C++ project.

For example:

Example Image

I'd like to know it cause I've written another program in C++ (little GUI) and I'd like to add this second GUI on the first one release with DirectX.

Thank you in advance
