You could make a 'grid' for you bitmap (for example 16*16 pixel sqares) and then do something like mouse_x/16, mouse_y/16 to get the coordinates of the sqare the cursor is in... If you need more 'precision', you could make a mask of your bitmap (I think some graphical adventures work that way). Redraw that bitmap but with only one color for each different object... when there is a mouse-click on the bitmap, just transfer the coordinates to the mask and see which color (object) is clicked on...
