What is an HTA?  It stands for HTML Applications, which allows you to wrap your scripts up in a graphical user interface, an interface replete with check boxes, radio buttons, drop-down lists and all those other Windows elements.  In this first of many tutorials, you will learn how to create your own HTA...leading up to creating other new elements such as check boxes, radio buttons, and drop-down lists.

Here's a good read on the subject: http://www.microsoft.com/technet/scriptcenter/topics/htas/tutorial1.mspx.  And then there's the HTA Helpomatic, a utility that helps you write HTA's.  It doesn’t actually write HTAs for you, but it does provide you with sample HTML code and some sample VBScript code that you can copy and paste into an HTA of your own.
