Correct, Arduino board is not a PLC but nevertheless there are 
manufacturers that add to an Arduino board everything necessary for it 
to be one, such as for example:

It may be possible, somehow, to convert the gambas code to C code and 
then compile it and upload it to the arduino board.
The FAST option does that with JIT as you can see in: 
https://gambaswiki.org/wiki/doc/jit#t2

That is, the IDE "makes" C source code and then compiles it.
So, if it is possible to get hold of this C code, it would be possible, 
in theory, to compile it with gcc since this compiler has avr support.

You right, using C is the best option, but is not the unique way to 
programing a controller. There are several alternative IDE's to program 
an Arduino board, some of them in visual form.
