Adding a padding or margin between widgets

Does anyone know if there's an easy way to add padding or a margin between widgets? Like for example I have a button that has an edit widget inside of it and I want the edit widget to completely fill the button except for either pixels on all sides. I know I can do it the retarded way by hard coding it but I'd rather not if possible.

The only way is to do this manually.

Alright, That's what I was afraid of. Thanks for the quick reply
