Hi. General flow is correct, but GTK+ does offer some functionality that may come handy in your case. (I'm commenting in a rather strange succession because Richard top-posted his reply).

Don't use movement events to monitor your position. Simply set text view's "has-tooltip" property to "TRUE" and connect handler to "query-tooltip" signal. Use coordinates provided by callback to find the word that cursor hovers over and then do the lookup. I think things should be relatively simple.
