Its true that devloping a full blown web app is easy.
But you must already know all the parts
Probably 2 or more languages
Two or three frameworks,
HTTP layer programming (get, posts, delete, updates),
A build server,
A dev server,
The prod server.
The web server,
The db server,
Register Domain Name,
Learn about DNS and DHCP
Router config to ISP
Oh wait, you also want what?
TCP/IP 6 support?
TLS 1.2 implementation?
Signed and Obfuscated code?
XML to Rest conversion?
You want WebSockets?
AWS instead of Azure, or perhaps Google?
You want Mongo instead of SQL?
Google, FaceBook, Azure and AWS autentication?
A web page that does everything Excel does?
You want the website to do the same thing as QuickBooks?
