Sure. Create a number of small text fields with behavior set to a  
behavior button and a target button. In the behavior button script set  
up mousedown and mousemove handlers to handle dragging (see the  
archives for how to do this), and in the mousemove handler include a  
'if the mouseloc is within the rect of btn "target then eatme" '. Then  
the on eatme handler in the card script takes the text of the target  
field and appends it to the display field and deletes the target  
field. In the display field, put a mouseup handler that hilites the  
clicked line briefly for user feedback then creates a new small field,  
sets it behavior to the behavior button, loads it with the line text,  
then deletes the clicked line.

If that's what you want to do. Not sure why you prefer this to just  
dragging the lines around to reorder them in the display field. I  
guess it's a game that you have in mind?
