Yes u can have pushbutton on application toolbar.
You just have to use the new pf status in your report program.
You should copy the 'STANDARD' GUI status from program SAPLKKBL using transaction SE90 >Programming SubObjects> Gui Status.
Execute this transaction to get to next screen. select status using checkbox. click on GUI Status --> Copy.
Enter your Z program name and the name you what for this status - you can keep it as 'STANDARD' to be simple.
Then you can edit the new status to add or delete buttons. This will also bring in the standard SAP ALV functionality.
Have a look at below code for using the new status.
TYPE-POOLS: slis.
DATA: i_qmel LIKE qmel OCCURS 0.
data v_repid type repid.
SELECT * FROM qmel INTO TABLE i_qmel.
v_repid = sy-repid.
CALL FUNCTION 'REUSE_ALV_GRID_DISPLAY'
EXPORTING
I_CALLBACK_PROGRAM = v_repid
I_CALLBACK_PF_STATUS_SET = 'SET_PF_STATUS'
I_CALLBACK_USER_COMMAND = 'USER_COMMAND'
i_structure_name = 'QMEL'
TABLES
t_outtab = i_qmel
EXCEPTIONS
program_error = 1
OTHERS = 2.
IF sy-subrc <> 0.
* MESSAGE ID SY-MSGID TYPE SY-MSGTY NUMBER SY-MSGNO
* WITH SY-MSGV1 SY-MSGV2 SY-MSGV3 SY-MSGV4.
ENDIF.
