Why can't InteliJ create a runnable JavaFX app using their wizard?

Its just frustration, creating a new JavaFX application through InteliJ does not run or build out of the box, there are things that need to manually configured which are confusing to new folks and what I can't understand if I was developing this product why would i not auto configure the JDK or prompt for download change the Java language compliance level required for JavaFX and do all this stuff that a wizard should do. Its so frustrating creating new template projects that can't run what is the purpose then?  How do I know what JDK to use for JavaFX what language level, can this IDE handle this for me?
