“Do you still want to get together?”

You made vague plans to meet an old friend of yours this weekend, but you haven't heard from her and want to check to make sure that she hasn't changed her plans. 

Do you still want to get together this weekend?

do you want to (do something)

Although this is a very basic expression, it's worth pointing out that this is the most natural way of asking this question. "Would you like to" is just a little bit more formal.

get together

This can be used as an intransitive verb:

We should get together.

Or you can specify who you're getting together with:

I'm getting together with some friends of mine later tonight.

This phrase is a good casual way to express the idea of meeting with friends. The word "meet" can sound too formal.
