Where to develop my project?

I can't figure out where to develop my project. I have been learning Java (6months), and php/mysql(few months). I want to build project, based on databases(like webpage/forum/etc)

And want it to be reachable from website and phone.

But I don't like php programming, I would love to programm this in Java, but I can't find info if it is posible, too just launch java swing application in web browser?

And maybe where else to program this? (Thinking about Android Studio, but then it will not be available on pc.

Hope, you can understand me. (English isn't my native language)
