It's possible to press the button for the next ability up to about a second before GCD expires and have that ability execute the moment it's available. However this does not seem to work in all cases. In particular when applying two buffs or off-GCD abilities in quick succession it seems there's no queue slot for executing a GCD ability afterwards.
