Glfw
GLFW is a free, Open Source, multi-platform library for opening a window, creating an OpenGL context and managing input
Glut
The [Open]GL Utility Toolkit (GLUT) is a utility library for OpenGL applications to put the platform-dependent details (e.g
Posters opengl menus

"Edit explained as i m guessing you are somehow forced to use glut but i agree with other posters glfw is a better option if you can choose" from question Usage of glutMainloop() and the other functions in OpenGL |

"Or if you re really focused on only doing opengl i may suggest using glfw which is the better glut but you ll have to draw the menus yourself using opengl" from question How to make a menu pop up after mouse release |

You could stop using glut;glfw gives you better control over the loop so that it s easier to do other processing from question Excuting the rest of my programme around glutMainLoop? |
|
I would recomend moving away from glut and freeglut;glfw is much more modern and easier to understand from question Compile and Debug GLUT under Visual Studio |
|
Between these glfw is much closer to glut in character -- a small toolkit for abstracting away most of the os-dependent parts so you can produce opengl programs with relatively little hassle from question How to start developing with OpenGL and C++, what tools do I need to install on windows |

Also much of your requirements is already handled by the various opengl utilities - namely glut and glfw;if you intend to stick with opengl both will do the job glfw is more advanced and provides more control from question How to structure an application framework |
