              Execute="immediate">
   <![CDATA[msgbox "You clicked?"]]>
</CustomAction>

<Control Id="DoActionButton"
         Type="PushButton"
         X="120"
         Y="100" 
         Width="56"
         Height="17"
         Text="Click Me!">
   <Publish Event="DoAction"
            Value="CA_ShowMessage" />
</Control>

Clicking on the button will show the following message:
