number of textctrl entries based on user's input

Hi list,

I'm new to GUI programming,so I'd like to know if what I attempt to do is
feasible:
a textctrl box a user is required to enter the number of input files
required and I'd like to generate a number of "textctrl" and radio button
widgets based on the upper textctrl. So if the user enters 5, I'd like to
generate 5 textctrl with their corresponding radio buttons.

Thanks,

Jaime
