What is the easy way to creat a GUI instance just like creating normal instance

You could probably try using cloud formation templates, in which you will define most of the normal parameters you use in the same process you follow creating normal instances. I recommend that option if you will be doing massive new builds of servers or need to deploy quick environments

You can make linux instance and install a tool like virtualmin to give your self a GUI control fo the server. I use this all the time an can be very useful. There is a learning curve but worth it.
