A few days ago I moved one of my personal domains to Office 365. One of the things I noticed is that you can create new documents without the need of a client application, everything is done by the Office Web Apps.
This is only possible from the Home page of Office 365. When you create a new document from within the document library itself, you still need the client application to be installed to create the document.
When I got back to the homepage of Office 365 I saw that it used the following url:
http://www.yourdomain.com/TeamSite/_layouts/CreateNewDocument.aspx?id=http://www.yourdomain.com/TeamSite/template.docx&SaveLocation=http://www.yourdomain.com /TeamSite/Documents&Source=http://www.yourdomain.com/TeamSite/Documents/Forms/AllItems.aspx&DefaultItemOpen=1
This URL can also be used on a SharePoint on-premises environment with Office Web Apps installed.
The CreateNewDocument page can be used to create Word, PowerPoint and OneNote documents. If you want to create Excel documents you need to use the following URL:
http://www.yourdomain.com/TeamSite/_layouts/xlviewer.aspx?new=1&SaveLocation=http://www.yourdomain.com/TeamSite/Documents&Source=http://www.yourdomain.com/TeamSite/Documents/Forms/AllItems.aspx&DefaultItemOpen=1
As you can see it makes use of another page called xlviewer.aspx.

What can you do with it?
You could add a HTML markup to your page with links to the documents templates, so you can create documents without the need of a client application. Like in Office 365.
Another approach could be to create a web part and check the available document libraries and document templates.
