Help in report UI and code

Question

HI Experts  ,
I need to create report and i need to help for GUI aspects (i want it to be looking nice ).
in the report i have 3 options (i don't know if radio button is the best way ) .
1. Read user attributes
2. create user attributes
3. create user values
if user choose to read attributes (which is defult ) the other option are should be deactivated ,
but when user choose to create he can choose one of the option or either both option ( 2,3 ) 
i need for that i guess 3 buttons .
what is the best why to do that from GUI aspects ,and code will help
I read lot of post on the forum but i get confused
Regards
Chris

HI ,
I am working to do that but i am facing some issue.
when i create TM i want to add new fields to the screen
SELECTION-SCREEN BEGIN OF BLOCK b1 WITH FRAME TITLE text-004.
SELECTION-SCREEN BEGIN OF LINE.
PARAMETERS: read RADIOBUTTON GROUP g1 USER-COMMAND u1 DEFAULT 'X'.
SELECTION-SCREEN COMMENT 3(15) text-001.
PARAMETERS  cre_zm  RADIOBUTTON GROUP g1  .
SELECTION-SCREEN COMMENT 21(30) text-002.
PARAMETERS  cre_tm  RADIOBUTTON GROUP g1.
SELECTION-SCREEN COMMENT 54(30) text-003.
SELECTION-SCREEN END OF LINE.
SELECTION-SCREEN END OF BLOCK b1 .
This is the code that i add
INITIALIZATION.
  LOOP AT SCREEN.
    IF screen-group1 = 'M1'.
      screen-active = '0'.
    ENDIF.
    MODIFY SCREEN.
  ENDLOOP.
AT SELECTION-SCREEN OUTPUT.
  LOOP AT SCREEN.
    IF cre_TM = abap_true.
      IF screen-group1 = 'M1'.
        screen-active = '1'.
      ENDIF.
    ENDIF.
    MODIFY SCREEN.
  ENDLOOP.
START-OF-SELECTION.
the problem is that when i choose also create ZM it the field appear ,
what i miss here?
Thnaks
