You will need to make bindings on the canvas items you create.  This is 
similar to regular widget bindings, except they apply to canvas items 
and uses the canvas subcommands.  You would mark the item for movement 
on ButtonPress-1 and move it with B1-Motion.

There are Tcl/Tk examples in the standard Tk demo that show moving items 
on a canvas (along with lots of other canvas features).

The following again are Tcl/Tk examples, but should be easy to translate 
(let us know if you hit issues):
   http://wiki.tcl.tk/1291 (list of some Tk widget examples on the wiki)
   http://wiki.tcl.tk/884 checkers, which has item movement
