Welcome to the Board!
You have several options on this front.
Create a UserForm that is called in a Workbook_Open event and use Option Buttons or CommandButtons to select sheets; create a blank worksheet with Forms or Control Toolbox buttons which allow users to select a sheets, etc.
There are a lot of ways to go, so can you specify what you're trying to do? I.E. Will you have a static number of sheets, or do you need to create an "on-the-fly" list of sheets from which to select?
Everyone else can take it from there!
Hope that helps,
Smitty
