I've created this Software/Desktop Application while I was working in Tech-Support company. I used PyQT4 for GUI development and SQLite3 as a RDBMS. The main reason why I used SQLite (and not other relational data base) is that SQLite is serverless. I also used a bit of Numpy and Matplotlib libraries for working with data (charts).
Main usage of this software is entering, saving (in certain template/order), showing and searching customer's data, description of the problems and troubleshooting steps. It also tracks your call duration which helps you to determine the longest calls and so on.
You are also able to change the time your shift ends.
Tickets information is available on View/Tickets.
Charts and Top 10 are available on View/Statistics, where you can see statistics for every ticket, created in certain year, month or date.
