You don't need a timer for that.  Simple call GetTickCount() when the word
is shown, and again when the word is finished.  The difference between the
two values will be the elapsed time, in milliseconds.

Pressing a button (or other control) is an action that relies on messages
being placed in, and retreived from, the message queue.  So no matter how
fast your timer is, the overall calculation for the reading speed will be
slowed down by that.  If your main thread is delayed in processing new
messages, your click actions will be delayed, and your calculation will be
inaccurate.

About the only way I can think of to get real-time results at the resolution
you are asking for is to use a global keyboard and/or mouse hook via the
SetWindowsHookEx() function in a DLL.  When the user wants to move on to the
next word, they simply press the keyboard, or move the mouse, or click the
mouse button (but not on anything specific).  The hook(s) can track the
hardware notifications so it can react faster than waiting for the message
queue.
