I have 2 problem in my program (source code is attached):-

1. When I run my program then I have lot of space at top,bottom,left & right space which I don't want at all.
2. Text Field size is not set (I dont' want to use fill=BOTH for text fields)

Plz modify my source with solution of my problem then return me..
