gmap google maps

I have created a world map with polygons overlaying certain countries using Drupal 6 and the gmap module. However, I cannot for the life of me figure out how to make those polygons clickable so when a user clicks on them they open a popup with the information about the country.

'width' => '940px',
'height' => '405px',
'latitude' => 20.0,

I'm not sure where I would build the check box form right now. would I use the menu system or what?
Has anyone tried anything like this?
