Getting Started tutorials are full of acronyms that obviously do not contribute to the basic understanding of the material and there are numerous errors in the instructions. For example, The Help->Welcome page offers a tutorial for a SWT "plug-in" that performs a window based "Hello World". The beginning instructions guide you through the requirement to import a "Plug-in Development > Plug-ins and Fragments" to import the SWT. I don't know which version of Eclipse is being used but my File->Import menu does not mention a plug-in option. Looking at the Forum thread for this "getting started" topic, the numerous comments bare out the difficulty with getting this SWT project to work even for the people that downloaded the source code with the project.
Now, what about returning to the Help->Welcome page screen? Hmmm, well using Help->Welcome returns you to the SWT project. Back arrow? No grayed out. Hitting the window cancel button? No that just closes help. Using the "Restore Welcome" link? No does not do anything. Reinstall Eclipse?
What about Help->Help Content->Java Development User Guide->Getting Started->Basic Tutorial->Preparing Java and making sure we have the right JRE installed? Hey maybe this why I cannot use jFrame. Now we are getting somewhere. But wait Select the menu item Window->Preferences? Well, that menu item does not exist. Preferences are under the Eclipse menu in my version of Eclipse. Interestingly trying to use jFrame I get the message that jFrame can not be used because /Library/Java/JavaVirtualMachines/jdk.1.8.0.jdk/Contents/Home/re/lib/rt.jar is missing. UnderEclipse->Preferences it seems to be listed except that under the installed JRE's it is shown as
/Library/Java/JavaVirtualMachines/jdk.1.8.0.jdk/Contents/Home. Obviously makes a difference but what is going on? Well, I have not got started even after a lot of very frustrating work.

A clear indication of what you were trying to do would probably be cheaper (indicating the roadblocks you ran into is probably fine if you at least get that part in there). Reading your original post in this thread, I'm hard pressed to figure that out, or find a question that doesn't come across as rhetorical.
