well this is easy dude.
Onblur or onchange over the textbox that serves as an input, you catch that
event and parse the input so you can get the desired number.
after that you choose in which panel/parent node you want to create those
textboxes and accordingly in your listener you can do :
for(int i=0; i < number; i++)
parent.add(new TextBox());
if you want to have names for your textboxes then inside your loop you can
do myTextBox.setName("myName"+i);
