Gambas doesn't have any way to make an array of controls graphically yet.  You 
can assign them to groups for handling of events, but that doesn't really 
give you any of the other benefits of control arrays.  The best I've come up 
with is to do it once in code and then treat it the same as in VB.  Warning: 
pseudo-code ahead, I don't have any projects handy where this is done.

public Labels as Object[]

...

(in form load event handler)
labels = new Object[10]
labels[0] = Label0
labels[1] = Label1
...
labels[9] = Label9

...

(then, in some other routine)
for i =1 to 10
 	labels(i).forecolor=Color.Green
next

If you have more than a handful of controls to be put into the array, it might 
be better to create the controls in code at runtime rather than using the 
form editor and manually putting them into the array.

In any case, you would then want to put all those controls into a group (in 
code it's something like mycontrol = new Label as Labels) so that you can 
handle all the events with one bit of code.
