LabVIEW NXG WebVIs let you create a web-based UI within the LabVIEW NXG editor. WebVIs are built on the standard web browser technologies such as HTML5, Javascript, and CSS. So, WebVIs are able to be deployed and then accessed from any web browser that supports HTML5, Javascript, and CSS. No additional plug-ins such as NPAPI are necessary to interface with WebVIs.
You could also create the web front end from scratch (what is done for you in LabVIEW WebVIs) if you are comfortable working with HTML, Javascript, and CSS. It may be worth looking at the
