Its one thing to know which version to use, its another to know why.
Linux treats the graphic system as an addon. Unlike M$, it does not use the actual Window objects to sending operating system messages (the reason that all Win apps need a window, even if it is hidden) but instead has a separate signaling mechanism. The graphic system in Linux is called X Windows. X by itself is extremely raw, and not very user friendly.
Sitting on top of X is generally a series of programs that handle everything from window decorations (Metacity, etc) to full desktop management (KDE, GNOME, etc). Its all a wonderfully beautiful sandwich with layer upon layer until you get the GUI you see.
Motif is a graphics package that was used to create older desktops such as CDE and OpenWin.
GTK is the graphics package that was used to build GNOME.
QT is the graphics package that was used to build KDE.
In the simplest form, you can think of these as widget factories attached to an API. (Yes, for you purists I realize this is not exactly accurate, but this is a newb and its close enough for his needs). Almost the equivalent of the Windows API. Motif, GTK, and QT are all supersets of X.
Most modern Linux systems include both the GTK and QT libraries even when only one of the desktops are installed. This is why I can run GIMP (also built on GTK) on a KDE desktop, or Kate (built with QT) on GNOME. However, Motif is not generally included any longer. You could technically add it on if you needed, but with modern systems, there really is no good reason to do this.
So know you know why
