# The Genealogist Part 2: Giving it a web-based GUI
In [part 1 of this tutorial](http://www.swi-prolog.org/pengines/Genealogist.html) we built a Pengines based web-service capable of serving up solutions to queries about family relations over HTTP. In this part we shall create a simple web GUI for our Genealogist application.
Here is the HTML we shall work with:
~~~~
The Genealogist
Query
Output
~~~~
We then need to make this HTML file available to the server. It can be placed anywhere from where it can be retrieved and served to an external browser, but we think that it sits most comfortably in the =|./apps/genealogist|= directory, along with the Prolog file.
~~~~
apps/
genealogist/
genealogist.pl
index.html
swish\
scratchpad\
~~~~
The application can now be tested. We don't even have to restart the server. All we need need to know is the URL pointing to the application. If you are running your Pengines installation as the default =|localhost:3030|= that would be:
~~~~
http://localhost:3030/apps/genealogist/index.html
~~~~
In [the next part of the tutorial](http://www.swi-prolog.org/pengines/GenealogistUpdate.html) we are going to implement support for updating the database of parent-child relationships.
