Applications in different difficulty

[bubbless]

Hi all.
I was thinking of what I could make next to improve my java skills
but I found it very hard to think of an interesting program.
I would like to do a request to post some ideas for applications to write depending on the difficulty.

For example, what applications did you write first?
What was the hardest application you ever made?
What would you really want make some day?
