I have to still add a "button" for loading on what I would loosely call the "interface" of my level editor. Once I do that, the level editor is complete. Than I can make the level select screen with this dialog.
I couldn't find out how to build the boost libraries, so I just downloaded the libraries pre-built. Even then, I had to go in and rename one of the lib files to get it working. But, it works now.
