In addition to Larries suggestion you (if necessary) should decide which
method to use to do "remote events", i.e. having your CGI output
something to the browser without the user having requested this
explicitly right before.
Here you need the CGI) to stay active without a pending request (e.g.
have it be an FCGI) and you need some java script in the browser that
polls for events, as HTTP does not (normally) allow for "pushing" an event.
There are several "standard" frameworks that build a GUI (including
Event handling) in the browser, but AFAIK none of them provides an
interface to Lazarus, nor does Lazarus support any of those. (There once
had been "EXTPASCAL", but this project seems to have died.)
