Dynamically resize a button

[petero]

Is it possible to allow a user who is running a finished stack to make the size of a button smaller or larger. Preferably by first holding down a modifier key.

The objective is for a caregiver to be able to resize buttons in an application for multiply diabled children who are now making on screen button selections by controlling the cursor with their eyes. Different kids have different control capabilities and thus the caregiver may have to make a button larger.
