When you click on the buttons 2D Nav Goal and 2D Pose Estimate all the rviz do is to publish a simple message on the specified topic. By default those topics are:

• geometry_msgs/PoseStamped on the topic /move_base_simple/goal in case of 2D Nav Goal
• geometry_msgs/PoseWithCovarianceStamped on the topic initialpose in case of 2D Pose Estimate

You are free to use any other publisher to send messages to those topics and therefore control the navigation stack either from your own program or from the command line using rostopic pub like:

rostopic pub -1 /move_base_simple/goal geometry_msgs/PoseStamped '{pose: {position: {x: 1.0}}}'

You can see which topics are called with specified button press in the Tools Properties panel window, which is usually localted in the upper right corner of the rviz. You can use this panel as well to change the default values for topics to be called.
