Write name to Macro addon?

[Baz4k]

This is for Classic

I am looking for a player frame addon that I could right click on a player frame and click an option to write a macro;

For example, say you are in a dungeon. The tanks name is "Joe". You could right click Joe's player frame and click "Set as Tank" and it would write a macro that like this;

#showtooltip
/use [harm][@Joe-target]Frostbolt

Is this even possible? I understand that Macros can't be written during combat, but something like this would be great to use at the beginning of the dungeon. This would be a way to get around not having focus...any help would be appreciated.
