GGAP is a frontend for GAP computer algebra system which works with GAP up to version 4.4. It provides a workarea a bit like that of classical Maple. Also, it makes easy accessing the GAP manual. After installation, if you find GAP is not initialing, or the data in the setting gets lost when restart, do the following which solved my problem.
Create a file call ggap.ini in the directory
with a content like this (change the path information)
rootdir=<Path to GAP 4.4 root directory>
exe=<Path to GAP 4.4 root directory>/bin/gapw95.exe
args=-m 32m -o 1024m -l <Path to GAP 4.4 root directory>
