Here is garage project and my deb
https://garage.maemo.org/frs/?group_id=1219
What is done:
Files are placed in appropriate places (may be excepting config file)
Command line utility which would understand if encoding is 72 (used by Russian operators) and handle it properly. In other case no conversion one.
Home widget - button, which executes query and shows it as a text on it. Pressing button would execute query again.
GUI configuration (press on configure button in layout mode)

Known bugs:
GUI configuration would work after
chmod 777 /etc/ussdWidget.conf
On some systems it would break desktop layout mode: in layout mode pressing on menu which normally sujjests what to add to desktop would stop working. The same code on my device works. I think, that some dependences are missing.
