You can make a GUI on Roblox by clicking the insert button on the toolbar, selecting "Object", and double-clicking "ScreenGui" you can then use this same method to insert various GUI elements into the ScreenGui object. Most GUIs require scripting to work correctly. If you don't know how to script, try searching Google for "Roblox Scripting Lessons" to find tutorials. Actually, there has been an update recently, and now there is nothing that says screen GUI. There is no way I know of to make a GUI.
