It is easy to implement as we have a decent API in KGuiAddons: 
KModifierKeyInfo. That's for example used in the screenlocker to show 
whether capslock is activated and IIRC there is even a datasource 
wrapping it. So doing a plasmoid should be fairly simple.

Just as an FYI: KModifierKeyInfo doesn't work on Wayland yet, but KWin 
has the information (in fact it is responsible for turning on the LEDs 
on the keyboard [1]).

[1] Which was rather difficult to implement as I also don't have any 
keyboard (neither desktop nor notebook) with LEDs.
