not sure what you mean, but there is a rest-ui option, when you edit the gui (press esc and choose the option for the ui layout).
if you mean, that the skill buttons don't appear where they used, then I don't know if there is a reset function, but if you press 'k' then you get all your skills up and with right-clicking you can replace the hotbar skills with another one (dragging and dropping).
hope this helps!

Right-click-dragging is needed to move items on your action bar (probably what you call "space tray")
