how can I implement them into a application, for example a text box

CreateWindowEx() or via a pre-designed dialog box.

For the class name argument in CreateWindowEx() you would use one of the predefined strings or atoms to create the control.

"BUTTON" for a button
"EDIT for an edit box (text box)
etc...

look them up on MSDN.
