Answer 1

In fact your reasoning is correct. An ASMX web service implements the SOAP protocol and cannot have any GUI interface whatsoever. Top design an interface of a web application in .NET you could use ASP.NET for example. So you could create an ASP.NET application which will consume this web service. By the way ASX web services are considered as deprecated technology and you should use WCF instead.

There are different techniques. However, its common to utilize Ajax requests to your webmethod via AJAX.

Here is an older walk-through but its still valid - http://dotnetslackers.com/articles/ajax/Using-jQuery-with-ASP-NET.aspx

It demonstrates two approaches using jQuery (which I recommend) and Microsoft Ajax.
