In the following image, you can see a screenshot of the current look of a "Contacts" panel I created. In the area I have highlighted (bottom) there are two buttons to add and remove contacts respectively. I am having certain doubts as to whether the users will find this technique visually appealing and/or friendly.

First of all is the current technique of making certain actions available to users working?
In any case, what alternatives are there?
How can I boost the user's experience through the alternatives? Why?
In the same way, is there a better way of offering a "return" or "cancel" action other than by inserting a button in the panel's header? (This doesn't apply to the Panel shown).
Any help would be appreciated.
