Simple LabView VI

I need a VI that does the follow: 1) A button (A) 2) A drop down box with a few items, a text box, and a button (B) 3) standard output When button A is pressed, an command is executed and results displayed to the standard out. When button B is pressed, it builds a string from the selection of the drop down box and text box and it executes a command line (System Exec VI) and then outputs the result to the standard out.
