How to generate labels and textbox on a form from a list in a sheet?

Hello,
In my workbook, each worksheet refers to a name (sample: city) and within the sheets, there are properties on this name. As a database in Excel, easily understood by users).
I created a form where you can insert new sheets with new properties using "labels" and "textbox" fixed. (A new worksheet is created with the chosen name and some properties are typed in textbox pasted in the new sheet).
However, they asked me to do more than that: I have a form that is able to insert new names (sheets); i need one that is able to insert new properties, ie: when the user enters a new property, a new line appears in each sheet dealing with such property.
Problem: When I want to insert a new account, this new property isn't be there in form, because the labels and textbox are fixed. So, I need a form textbox and labels that vary according to who is on a list (without knowing how many words are on the list) and, finally, pressing enter, your entry will appear in the new worksheet Textb ahead the names of the properties.

Thanks Ross.
However, a listbox solved my problem.
I didn't know listboxes, so I was finding how to print many and unknown words in labels... So, a listbox solved it.
