OpenGL Window

I am trying to make a game in OpenGL. When it comes to menus, I was having a hard time making buttons and stuff, and I knew that I would need listboxes and such. So, I decided to use a standard window for a menu. Now I know there are several different ways to do this. One would be to make a seperate window, to hide when I am playing the game, and show when I need it. I tried this at first, but came up with some errors I couldn't fix. So I decided to have it check a variable to see if it should create a opengl window, or a regular window when it was time to make the window, and then have it kill the window and make a new one with the changes to the variable whenever i wanted to switch windows (something like this is already being done when I try to switch from fullscreen to nonfullscreen and vice versa). This didn't work for me. So, I have come up with 2 new ways to do it. One is to just have the OpenGL window create the buttons in it for the menu and kill it for in the game. This seemed to me to be overly complicated and not necessary, along with the fact that I have tried something like this before and the buttons, edit boxes, etc look ugly so to speak. The second way is what I am now using. I create a child window for the opengl window that takes control of the window and has all the necessary stuff in it.

I made changes and got it to compile with my new idea. I have it starting off in the OpenGL window. When I click the button to make it switch to the menu, it makes the cursor visible again (like it is supposed to), but the window doesnt appear. I know it isn't just not showing up, becuase the window isnt getting messages. Or maybe I have it messed up so that it won't get messages.

My code (I have other files in the project but mostly they have to do with 3d models and aren't in use)

it cant be compiled without the font texture or the header file, if it is necessary to compile it, just ask and I'll post them. however, the parts for loading fonts can be commented out.

Anyway, my question really is: Why does it not show the window? And is this the best way to go about making a menu?

I am using Dev-cpp 4.9.9.2. Much of the OpenGL code is not mine, I am using it as a starting off point.
