Is there a widget / GM script or anything out there, which I can intergrate a :to do" list with gmail account ?

or how about with the google calendar??

i think that soon enough Google NoteBook will integrate with Gmail. just wait and see.
but you do have todo list on Google Desktop. i dont know if it can integrate with Gmail. i doubt it..

Here are some Google modules for todo lists:
