Go to se80 and give some program name, (in attributs select type as MODULE POOL) it creates all PAI n PBO modules automatically.

step 1: Rightclick on pgm name and select create -> screen

(give screen number).

Step 2: Give short desc and press layout button.

(it displays the GUI screen)

step 3: place two label box , text box(name it as io1, io2) and push button ( name it as print, exit).(give name for all the boxes.(dont forget to give function code for push button)

step 4: save and activate it.

step 5: double click on the screen number it shows both PAI and PBO modules. Double click on the PAI module and type sample code like this:

&----

*& Module USER_COMMAND_0100 INPUT

&----

text

----

DATA : IO1(33), IO2(33).

module USER_COMMAND_0100 input.

CASE SY-UCOMM.

WHEN 'PRINT'.

LEAVE TO LIST-PROCESSING.

WRITE 😕 IO1, IO2.

WHEN 'EXIT'.

LEAVE PROGRAM.

ENDCASE.

endmodule. " USER_COMMAND_0100 INPUT

step6: create transaction code for it. right click on pgm name and select create->transaction.

(it is bcoz u cant execute module pool program directly)

step7: again right click on pgm name and select execut->direct processing to execute your program.

Hope it guides you.
