Generating HTML Code Using ASP.Net Like In a WYSIWYG HTML Editor For a SharePoint Web Part

I want to know that is there a way to generate HTML code using ASP.Net in C#? Like when I click a button both open and close tags should generate with the attributes like 'align', 'class', 'id'.

As an example when you use a Web development tool like Dreamweaver or Frontpage they both have WYSIWYG HTMl editing capability. The same thing should be done using an ASP.Net web app so that I can modify it to use as a SharePoint Web Part within a SharePoint Site.

So this will be used as an alternative to the Content Editor Web Part and avoid using the Script Editor Web Part that both comes with SharePoint 2013.

Is it possible to generate the HTML using an ASP.Net web application and use it as a custom build SharePoint WebPart within a SharePoint 2013 site?

Thanks and regards,
