GIMP :: Create A Custom Tool / Run Script At Cursor

Is there a way to have a custom tool that executes commands where I point?

I'd like to have a tool that where I click takes the foreground color via pipette and in the same spot immediately applies "fill" with the settings the fill tool is set at.

Script pseudo code would be:

get cursor position use pipette at cursor pos to FG color apply "fill" at cursor position

Can that be scripted?
