Unfortunately, the guide I linked to above is about as easy as it gets and there's no GUI. If you have the basics in place, adding a button combination with the 'B' and 'A' set to act as 'start' would look like:
--ui-buttonmap b+a=start
It should be noted that the learning curve for all this is pretty high. However, it does get easier over time if it's something you want to explore. Also, while handy for Emulation Station, this really wouldn't be ideal for game play, as there are plenty of times where any two buttons will need to be pressed to trigger a game event and the game will only ever see your chosen combination as being the 'start' button. Of course, the mapping can be disabled once a game is launched, so there are possible work-arounds, but you're always going to be at a disadvantage with so few buttons.
