You are terribly vague in what you want to do, sort of like the Obama Care website it seems? If this is to be an internet based application then you should consider the following:
- what do you want it to do?
- How many users will be using it any one time?
- Will any data be saved and if so what database will you use? If this is a "real" system then either Oracle or MS SQL Server, stay away from MySQL as it has terrible security. If you want to use a "cloud" system, you will be milked dry!
- Where will the application run, should be on their own app server, on it's own sub net.
- Where will the database run, on it's own server, own sub net, etc.

Finally, who is going to run and tune and manage this since it is not something you can easy do w/o some experience. Several years ago I had a husband and wife in a couple of my computer business classes and they wanted to do this and had little experience. They got a loan, hired a couple of experts and now have "On Line Booty Call" running well!

Good luck.
