I have created a new project using the Create New Project Wizard, by choosing “create project from scratch” but it’s completely empty (no java classes at all, so I manually created a new swing form inside the empty project).

In many other IDEs I have used there is a way to click once, and get a new “new Gui project”, and I usually expect it in the “File -> New Project” wizard or something, comparable.

There is a new project wizard in the IntelliJ IDEA IDE, but it only seems it can create a blank project, and then I can manually add a form to it. So I did that. But then, that lacks any of the usual Java code that you would expect it to have, to open up that form and show it as an application.

I am trying to understand the features and capabilities of IntelliJ IDEA, and it seems strong as a very fast and efficient editor and debugger and build system GUI wrapper around the ANT build system, but I was wondering if there are more “RAD” features that I have merely overlooked. I have done a bit of googling and reading the docs, but I haven’t found much about using IntelliJ IDEA to build a GUI application in Java.

Where I’m currently stuck is when I tried to build and run my empty project with an empty form in it, and I get to some kind of “Run” target configuration screen, and I tried clicking the [+] icon, and adding “MyForm01” which is the empty swing form I created, and it says in a dialog box “MyForm01 is not acceptable”. I know enough java to know that the basic “GUI app skeleton code” is not being auto-generated by the IDE. I could go and copy and paste something from the internet, but my interest here is in knowing whether the tool can automatically be used to build a GUI, with a workflow as simple as other RAD-style GUI builder tools, including NetBeans, which is the java tool I am most comfortable using, or Delphi, which is my main everyday tool, which is Pascal based, rather than Java.

    There is no such thing as GUI project in IDEA. You can add GUI forms there at any time you need, just by RightClick -> New -> GUI Form. You can create GUI app from it just by adding main() method into the form binding class. IDEA does the job for you if you hit Alt-Ins (or menu Code->Generate) when in the binding class editor. The only requirement for this is to place correct name for the form’s root panel.

    You also should may want this manual to discover some other things: https://www.jetbrains.com/help/idea/designing-gui-major-steps.html. Anyway, the GUI builder is pretty intuitive.
