Just a case of using the OpenLink Ajax Toolkit  [1] :-)

The RDF Browser are just an example of an application built to 
demonstrate the Ajax Database Connectivity Layer of OAT (i.e. direct 
access over Javascript and HTP for SQL, XML, and RDF) and the OAT's data 
aware controls that use the Ajax DB layer [2].

The Form Designer is sort of like ACCESS in that you bind controls to 
data sources, set aesthetic attributes, and drag and drop on to your 
design palette.  If the demos and source code aren't clear enough, I'll 
try to knock-up a mesh-up movie based on the Form Designer and RDF 
Linked Data.

OAT is an Open Source Project [3].
