By the way you worded your question I'm assuming you are looking for a no coding visual html5 website builder? I never tried this one but it looks like what you might be looking for:
There are other software's out there like Adobe Dreamweaver that give you the option to build a website without coding but by the time you learned how to use them effectively you could have learned how to hand code your entire site with notepad. lol
I should have first asked you what type of business is this website for?
If you are going to sell stuff online you will need more than a html5 website. You will need some secure php scripts, and a database. If this is the case you might want to use a CMS (Content Management System) like WordPress, Joomla, or Drupal. Then just find some open source store plugins, a free theme that you like, and modify it to fit your needs. Come to think of it this might be the best way to go for any type of business. That way it will be easier for you to update, and manage.
Anyway I hope this helps, and good luck with your project.
