This can be quite easily implemented in pure Tcl. I've written something
alike for my last project.

There was a concept of "operation" which have name, command and keyboard
shortcut as properties. Operations can be enabled and disabled.

If you want to add operation to menu, just say
operationMenu $menu and it would perform $menu add command with all
appropriate parameters, and also remember than this menu entry should be
enabled/disabled along with entire operation.

Same thing with operationButton command, which allows to specify
alternate (typically shorter) text, and/or image.
If either of them is specifed, full name of operation is used as tooltip
for button.

There is also commands to disable/enable groups of operations.

May be I should polish this code and submit it to something like tklib.
