No.

PostgreSQL 9.4, table:

CREATE TABLE public.foo
(
    id text COLLATE pg_catalog."default" NOT NULL,
    data1 text COLLATE pg_catalog."default",
    CONSTRAINT foo_pkey1 PRIMARY KEY (id),
    CONSTRAINT gerp1 UNIQUE (id, data1)
)

1) Right-click, Create index

2) Name: xxxx

3) Access method: gist

4) Add column. Select id (note the opclass field is not enabled)

5) Add column. Select data1 (note the opclass field is not enabled).

6) Click save, and behold the following error in all it's glory :-)

ERROR: data type text has no default operator class for access method "gist"
HINT: You must specify an operator class for the index or define a
default operator class for the data type.
