This tutorial assumes familiarity with Windows.Forms application development in Visual Studio 2005/C#, and at least basic knowledge of OpenGL. It also assumes a top-to-bottom readthrough; it is a guide and not a reference.
To begin with, it is quite a different approach one has to take when designing a game/application using the GLControl in a Windows.Form compared to using the GameWindow. GLControl is more low-level than GameWindow so you'll have to pull the strings on for example time measurements by yourself. In GameWindow, you get more for free!
Just as in the GameWindow case, GLControl uses the default OpenGL driver of the system, so with the right drivers installed it will be hardware accelerated. However, with large windows it will be slower than the corresponding fullscreen GameWindow, because of how the underlying windowing system works [someone with more detailed knowledge than me may want to elaborate on this..].
If you come from a "main-loop-background" (C/SDL/Allegro etc.) when it comes to coding games, you'll have to rethink that fundamentally. You'll have to change into a mindset of "what event should I hook into, and what events should I trigger, and when?" instead.
