Coding, wich nice Project? Ideas

Hi,
I do coding with Lazarus Pascal.
I'm not good at coding, but it is not bad..because it helps if you have problem with concentraition and this..
Some easy Programs like
1.Learning Calculate prices, and check the time how long you need somthing like
30$
- 25,67
======

Or
2.quicker learn the small and Big 1x1 with time Check

3.Cost calculator an documentation for Energy, Water....with Diagrams but NOT in Excel

4.
A list of readden books, with a list, when start reading, when end, how many days you need for how many sides...

Maybe in Lazarus Pascal, C, PHP or Java I have to see..
