I'll clear out your to do-list. Add the following code to your interface XML:

XML code:

---

<Control xsi:type="ButtonControl" Id="MyButton">
    <Position /> <!-- Use your own values for this one -->
    <!-- Any other code? -->
    <Attributes>
        <IsDefault>true</IsDefault>
    </Attributes>
</Control>

---

That should do it.
